Dude let me just say. My story is a bit rough and very long. So when I was 24 I believe idk it was in 2012, I met this guy older guy he was 34. Very handsome and quirky which I loved about him very intelligent and what a great persobality he had. He was also desperate and lonely and I was his rebound guy. I knew it but I wasn't experienced. His ex was a guy his age very handsome very masculine looking very high maintenance guy, both worked in the medical field. I was this skinny kid working a low paying job going to school just to waste time. Had my head all over the place. Anyways I wasn't so into my guy until maybe two months into it he starts ignoring me, he starts almost rejecting me. And one day he totally rejected a kiss which I'm like WTF man????!!!! Prior to that he started mentioning his ex a lot and he even bought a black cat and named it mittens like his ex's cat. While I'm busy at school and work he begins to try to stalk his ex and also tries to "find his ex in someone else" someone who looks acts and feels more like him. Trust me. Me and his ex don't look anything alike in fact my dude would make me feel lesser comparing me to his ex.. he would inadvertently do that to me. So me being ignored caused me to want him and to fall for him. No matter how much I tried to act tough like it didn't matter it hurt. And I tried to casually get back with him much to his disdain and he didn't have the heart, Na he didn't have the balls to end it, and I didn't know better. I liked the way i felt around him and I missed how he used to look at me before things went south. Mind you this relationship was no more than two months. Anyways I go to the extreme to one day take a train, and a bus and walk for over an hour trying to reach his apartments. I made it and hid in the bushes stalking my BF for hours and texted him he claimed he was away and busy with family.. I was sitting hidden in the bushes outaide. I see him pull up, he walks to his apartment. I text him and he claims he isn't home. A fit looking guy walks to the apartment and my BF let's him in and they stay there for about 15 minutes, my BF DIDN'T respond to my text until 30 minutes later claiming he was at work.. my heart was sinking I didn't know what to do or say, I was hurting yet had an excitement as I never felt like that before. I choose to confront him and I knock on the door which obviously has people inside, i call and his phone rings as he loves to keep his iPhone with sound notifications.. he has no choice but to open the door after about 3 minutes. He comes out with much disdain in his face and not happy to see me but fakes it. The other guy walks out past me, hot looking guy, but now I feel like crap. He asks me if I would like to walk in. I begin to bombard him with demanding questions to tell me what's going on, until he snaps and lays me out with a bunch of insults and screaming. He really let his venom out. His words really broke my heart. It all comes down to his ex. He adds that I was a mistake and that in fact I disgust him. I with whatever little dignity I have left I walk out.. I really stall. I want him to tell me to not go. He feels bad but feels relieved. I only served him as a companion because he is scared of being alone. He only used me for that, for THAT. Just for a companion because he is scared of being alone. And that sucks. 
When you are young and a grown man fucks with your head and your emotions. With your ego. You don't know how to react or how to take it. The same way I came, I left. He didn't offer to drive me home knowing the lengths I went through to get there. I was truly asking for pity from him. I didn't need a why, he let me have the why the most venomous way possible to make it clear. Enough to make me not want to come back. Every day I wished he would text me. And days went by and I envisioned him going to work every day, with a look of "I have things on my mind yet I am free" on his face. I was at least happy that he hopefully got over his ex by him dropping the damage on me. 
He finally IMs me months later much to my heart exploding almost. He asks if I'm ok. He claims he is suicidal. I give him a piece of my mind but to no avail. All he cares about is his ex... I feel bad for him as I know he isn't a bad guy, he wishes me well. But then I turn real evil. I start reliving everything and my first goal is to fuck his ex. Which want surprisingly hard as his ex a very handsome middle eastern fit guy in his 30s loves to fuck guys in their 20s like I was. I fuck him and make him my bitch. He loved every second of it. And we keep doing it. But then it evolves to more. I want more I hit the gym hard, get in shape get my body hard, hit the clubs start really going down the road like almost everyone else.  
I soon forget about my ex, I keep getting into a lot of crazy stuff and three years later my ex hits me up via an online app.. his handsome face really strikes a nerve.  Shows me his cock and average body.. I show him what I look like now and I want to show him me fucking his ex.. I'm dying to show him bro.. I hold back. My ex is full of shit for a guy his age. He is going around looking for guys who lift starts giving me BS about some guy he is with, mentions his lovable fuck able ex.. just like he did when he was with me, he is about to fuck with someone while being with another guy because he is bored of him. This dude is garbage but he acts like an innocent man child. 
I tell him it's me. I don't send him the pic of me fucking his ex. He likes what he sees in my new self. Wants to catch up. This upsets me. I'm mad. I say no its better if we dont. But I decide to tell him my taste has changed and now I'm into muscle guys. Guys who lift and look like bodybuilders. To which he said "Oh. Sorry ti hear. Well hope you find happiness in that. Peace." 
One day while at a club his ex was there and we dance and make out, we used to do that very casually and HE was there watching me make out with him and dancing with him and other guys. I see him and I stare at him while he makes out with me.. it drove my ex wild. I could see his pain yet he was turned on. The Arab saw him and said Na let's GTFO of here.. gives him a fuck off look, and my ex looks in shaken up and disturbed, he absolutely didn't expect this horrible yet exciting surprise. Me and the Arab enjoy talking shit about my ex. We brag about blocking him. We brag about him being a creep stalker and we make him out to be a lesser male loser to a bunch of other guys who laugh at him. We really drag his name through the dirt and enjoy every second of it. That was mean. 
Eventually I move on with my life and try to stay away from online apps or websites. I begin actually dating guys. I find myself being victim of the vicious cycle. I fuck guys and leave them. I can't stand them being around me and I feel so relieved when I dump them, and I walk away like I got problems of my own already.. much like my ex. This continues for a long time. Loneliness starts settling in. 
Suddenly one day two years ago i am no longer haunted. Got a new job. Found my hobby playing baseball and soccer. I go on and finally and to this day, get my head clear. I'm fucked up in many ways but it's safe to say, my issues with him are no longer a thing. Just an old memory. I feel healthy now. 
On the Twitter app while seeing my messages, twitter was fun back in the day. I find an old message from him from when we used to trade phones and pretend we were each other and answer each other's messages. I want to contact him to really catch up. Maybe to apologize because I was immature. Or maybe just to straighten things. I load his profile and quickly glance at his pictures, he seems normal as usual. But I know he is into some strange things. He did drugs but didn't like alcohol. I liked alcohol but didn't do drugs. I decided that na. 
I'm good now. I don't need to catch up, or apologize, or straighten things out. It has failed in the past, but that's beyond the point. I'm much older now and I don't need to prove to anyone anything. I'm a Man now. I got my life straight. He needs to straighten his own life on HIS own. Doesn't involve me. And I do not need him or need any form of contact with him. Deleted his message and done. 
Hope this helps
