But giving me his schedule and a free drink? What does it all mean? I'm going crazy here!
It means Nothing.
Well, I am wrong. It means that he is a nice guy and is a good sales person.
My point here is that you like the guy and you are Very Willing to Read Into Things. I've done similar things, examples of which I will not burden you with. Ok, I will with one. One time, I was doing a paper with a guy. I liked the guy. At one point our knees touched for a few minutes. I was Super Ecstatic! It definitely meant something! (to me). When my counselor said "it didn't mean anything, your knees just touched", I did not get him. I looked at him with dumbfoundedness, like "what do you know, you weren't there". Only later I've realized what he meant. It was 'nothing', a non-issue. Our knees touched because we were in proximity with each other, and the guy did not pull away. It didn't mean that he was into me. Unfortunately.
So what do you make of this and how do you deal with this situation. I say do this --> take things to the next level. Keep taking things to the next level until it becomes clear to you and to the guy that you have something together.
So how do you take things to the next level. Here you are the best person to figure it out. It is a creative process of figuring out what to do next. Give the guy your website and or email, and invite him to check it out. Or if you are able to, give him your phone number and tell him to call you when he is available to hang out together. I've seen people do this before, so that's perfectly acceptable. The key is to act casual and without being star-struck with your hands shaking. If these don't work for you, make something up that will.
EDIT: letter ? letter is a bit much. In book "Running with Scissors" the guy describes how he wrote a letter to a guy working at a coffee shop. (Coincidence? I think not ??). Author then left and watched from outside. The guy read his later, wasn't sure what to make of it, showed it to his friends and then they all laughed about it. That was incredibly embarrassing. The author says that being gay and not having a role model or something is that he didn't know what to do, and even more important, he didn't know what not to do. Apparently letter backfired on him and it was a thing on the "not to do list". I suppose it is different for everybody, but letter is a bit ... much in my opinion. If the guy is already INTO you for sure, the letter is probably fine. But with the possibility of him not being into you . .. it is definitely awkward. Although, you never know what may happen. If he doesn't mention it though ... he's probably not comfortable talking about it and is therefore probably not ... that ... interested.. ooh, it hurts to even say that.
