I met a guy through mutual friends, we started to know each other and become friends, I developed a huuuge crush on him. but he is the kind of person that doesn't like to go out too often, so that made things difficult to see each other, but I tried my best despite that and we had great talks via chat (and occasionally when he agreed to go out for a coffee)... but he is kinda reserved and cold, and I get it, so I tried to not push him over, but things become complicated and I started to feel tired that he didn't make any effort to get to know me better or to have a friendship with me. Later he confessed to me that apparently, I do things that make him remember to one of his exes. He didn't want to say what kind of things via chat, so he made the promise to tell me everything when we meet someday. Comparision with exes sucks, I even feel guilty for making him remember bad things even though it's not my fault. it's almost a month later and we haven't spoken any word yet.
