I literally see myself in this guy and I see himself in me?

[m.i.s.s.]

Like how a wife looks at her freaking husband like one without the other is like something getting taken away from them. So why the f*** did he never become bf/gf? He even STAYED single the whole time we knew eachother (2 years) and right after I stopped talking to him he got a girlfriend and right before I started talking to him he dumped his ex. I don't think I was his rebound girl BECAUSE at 1st I didn't reciprocate towards him when he asked me out on a date I just thought we were friends (he didn't say it was a date until after I said yes). Was he just looking for sex? He still seemed like he appreciated me though. Like you look at us and think we're like special to eachother or something but he never like did anything. So, idk what was going on. And he could have gotten a girl anytime because he was really attractive. We started talking to eachother less and less and didn't make anything out of us. But I saw him recently with a friend and he seems different than the 1st time I 1st met him like there's a difference after I met him like I can see I rubbed off on him or something like we changed. And I also know it's the place where we're from like guys from that city are notorious for being that way (w/the girls they like) but I don't understand it. & also I met him through a friend and I would have never met him if it wasn't for her and she's kind of a bad friend so should I just stop being like that ("bad" to be with the "tough" crowd of people......even though he didn't like her). Idk how to explain it. Him and I had more in common than my friend & I.
