So my ex bf's best friend and I have kind of liked each other for awhile and we hung out for a day and it was just perfect. I couldn't have asked for a better time. We talked for a few days after that and it was very clear we still had feeling for each other. Once school started he distanced himself from me. I could understand cause of my ex and everything but he said we would always be good friends no matter what and he never wanted to lose me as a friend no matter what the situation was. As months passed he suddenly stopped talking to me all together. I tried talking to him but he'd just ignore me or treat me badly. I still have strong feelings for him, but he only talks to me when he wants something(not sexual). I feel like I should talk to him about it but I'm not too sure what to say, any ideas? Why is he being like this?

I think he knows that he doesn't want to cross the line of friendship, therefore he is distancing himself from that temptation. Friends come and go in your life, especially mutual friends of an ex. Most of the time, it is for the best.

He probably does not want to ruin his bromance with his best friend because of you, but he if he still comes to you for things then it means that he does still has feelings for you, he just does not know how to go about it. It best if you let him keep coming to you, you should play hard to get and let him keep coming on to you so you would know if he really likes you or not. Also being that he is your ex best friend he would know a lot of good and bad things about you being that your ex would tell him everything. There could be something that keeps turning him away from you it could be tha your ex said something to him so he does not want to go after you. Or he does not want to deal with the drama if he goes out with you knowing the boy code is don't go after anyone's ex.
