Someone in r/relationships suggested to post here. 

My ex boyfriend of over two years broke up with me out of the blue right after Christmas. He said he was just too stressed with school and couldn't handle being in a relationship anymore. We had been taking marriage and moving in together and suddenly he was gone.

He told me he wanted to be friends and be together again when he got his crap together with school. We talk every once in a while over text, but he always stops talking to me in the middle of conversations, out just blatantly ignores me. He texted me for the first time in two weeks today asking me about my health (I have been somewhat sick the last year) and then suddenly stopped talking to me in the middle of the conversation.

Tonight, I saw him for the first time since we broke up, and it wasn't on purpose. I have asked him out for drink or to talk once or twice, and he just tells me he has no free time ever and it won't happen for a long time. I ran into him tonight at the mall with another girl. I saw them coming. They were laughing and walking extremely close together. My stomach dropped. I can't imagine being with anyone else, and here he is with a girl from school. He walked right past me, gave me an awkward wave and kept moving.

I want him still. I have resisted the urge to contact him and ask him about it. I feel like it wouldn't be my place to ask. I had this idea that things would get better and he would come back, but is it pointless to wait? He clearly doesn't miss me. I don't know what to do or what step to take next. Any advice?
