I live outside of Pittsburgh and my county has no LGBT support other than PFLAG. In fact there is literally only ONE gay bar and it isn't even open until 9 PM Tuesday through Saturday. Even then no one will talk to me. I have no idea how to start conversations either. And I basically am afraid to even apporach new people and talk about myself because I think that they'll abandon me like everyone else around me aside from family tend to do.
I'm 29, I live in PA, and I'm willing to accept practically any guy as long as he isn't a drug user, an alcoholic, or will physically or verbally abuse me. I give hints that I'm interested in guys online and I am polite and respectful and they still abandon me. My loneliness seems to be getting worse because I tend to buy more unnecessary stuff whenever I have money even though I KNOW I do not have room for it all.
Maybe you should
talk to them instead of waiting for them to talk to you?? You gotta grow a pair and just do it. A wise man (my father) once told me, ask and ye might receive, don't ask, and you will never know. That is to say, rejection is a part of life which you have already experienced, but if you don't even pursue what/who you want, you will never know what will happen. Why does someone being not interested in you hurt your pride so much at 29 y/o? You should seek to understand that and grow from it.
Conversation Starters:
1. That's a nice hat/watch/shirt/shoes. Where did you get it/them? Cool my name is XXXXXXX, what is your name?
2. Oh I see you are drinking xxxxxx. Are those good? I'm more of a XXXX(whatever you are drinking) myself. Maybe I'll get one next, btw my name is xxxxx, what is your name?
Ok, you still have not told us anything about yourself, what you like to do, or what kind of man you are. Do you literally give a "hint" to any guy between 18-99 online who does not explicitly state they are abusive or an addict? I am sure you have a more detailed selection process and you have shed no light on what it is. What does a "hint" even mean? You have basically told us nothing we didn't already assume...
The fact that you don't even have an idea of what kind of personality or interests you want in a potential significant other shows that you don't know anything about YOURSELF.
At 29, that is a problem. One that should be immediately addressed. I suggest actually writing down on pen and paper who you are in 3 sentences. These may change, but at least you will start to understand how to express it and start to recognize it.
Fuck hints. How many guys have you asked out to dinner or on a real date from online?
They are not abandoning you, as
they owe you nothing. Don't expect them to think they owe you something either. If there isn't a match, there isn't a match.
This is how dating and meeting people works.
How far out of Pittsburgh? Maybe consider moving to Pittsburgh, halfway between, or just going into the city more often to meet people in person.
Who are your friends? Have you expressed any of this to them? DO you have any friends? What is your profession? Can you find that opportunity in Pittsburgh?
Maybe, everytime you think you are going to buy something because you are feeling lonely, take that money and buy someone a drink at the local gay bar or make it a point to ask someone to dinner from online and say its on you? Just a suggestion as to how you could use that habit to your benefit.

I hate to say it though, but I largely agree with TX-Beau. Seek some therapy if you can afford it.
