Search Results: trying too hard to get her back

I met this guy on a dating site a full year ago. We never had sex and we went on a total of two dates.
(The second date, I went to his place and we smoked weed. I had an edible that ended up being too strong for me and I actually blacked out and had a few panic attacks.
As embarrassing as that was, believe it or not, he was still into me and wanted to see me again.)

Shortly after that, I left the state for my own personal reasons (this had been decided before meeting him), and he made a point to keep in touch with me. I am moving back now and he still texts me and apparently hasn't really been with anyone else (so he says). I would have expected him to move on or start dating someone else and forget all about me but he hasn't.

But what leads me to believe that he just wants me for sex is that, during the span of my absence, the only reason he would text me is to tell me he was thinking about me sexually. There was one time we talked (texted) about politics but it was short-lived because I got distracted. This is pretty much the only time I can remember him being interested in talking about something other than sex. I have asked him about work but he has very little interest in talking about himself. He also never asks about what I'm doing with my life or shows much interest. Mind you, I usually don't text him first, and I know that texting is not a good indicator of human interpersonal interaction, but we've never talked on the phone before due to the casualty of our previous encounters so we never established calling as a precedent. Now he's been texting me asking when I'll be back.

Do you think he has waited all this time for me just to have sex with me? He is a confident guy and probably wouldn't have to try too terribly hard to get another woman. I just can't imagine a guy waiting on a woman for a year whom he had only gone on two dates with, just to have sex with her.

There's this guy (A) who I know is very attracted to me and I have a strong feeling that his affections are pretty deep. He'd get a bit protective at times and the strongest takeaway was during out last meeting (throughout which he kept trying to brush against me, lean into me etc.) where his eyes suddenly softened (kind of like doe eyes) suddenly and he looked at me in an endearing way (while also softening his voice). It felt a bit too intense. I also had a hard time maintaining eye contact w him during that time as he hardly looked away.

We met in a group setting 2 days later and another guy (B) in the group was paying me a lot of attention. I knew B was interested me and I think it was apparent to others as well. I was friendly enough but I didn't engage in anything. B is very accomplished and it's pretty obvious that A holds his opinions in high regard. I know A has insecurity issues - he's so fidgety around me and would constantly apologise for things that he shouldn't have to. He has a slight anxiety issue too.

In any case, he kind of backed off in a sense that he was way more passive as compared to when it's just us 2. Even though he was clearly listening in on the conversation between me and B?

Could it be because another guy whom I think he holds in higher regard is hitting on me?
