I’ve had a similar experience emotion-wise. I mean, I didn’t have a relationship with this person, but it got close to that.
I’m still at the point where I want to know why the person is like that, but I’ve accepted that I’ll never get the answer from him. However, it would be nice if we can hear the viewpoints of similar people, such as a guy that is similar to the guy that you’ve been talking about. Sometimes I think about asking about my guy with people who also knew him. Sometimes they don’t know that much, and sometimes they’ve seen other sides, and it makes me think “no fair! I wanted it to be as simple as that!”

Seriously, is there no one, no one at all, that posted an article here or there somewhere that explains the behavior of PEOPLE LIKE THAT?
At least I no longer and will not, ever, allow myself to message him. He’s actually a lot more silent than I, anyway, so it would only make a fool of myself. I’ve only ever sent messages with good-intent, but he’d only sporadically reciprocate and confuse me, occasionally being mean, and dodging questions, while getting information out of me. There were times when he was nice. And I feel stupid to have fallen in love with him of all people. And I wonder if he feels the same way about me. That he also felt stupid for ever considering giving attention to the likes of me.
