My boyfriend and I have been dating a little over 2 years now. His ex however wants him back after 2 years.

Yeah... I think you'll need to add a little more to this if you want anyone to be able to answer you.

What does your boyfriend think? Are they in contact with each other? How old are you both?

He thinks she is crazy. He said he is done with high school so he's trying not to be a and just give her the small talk and they haven't spoken since last Sunday. The only contact they have is Facebook she lives 4 hours away. He is 21 I am 23.

You do nothing, so a ex wants him back, but my issue is why he is still talking to her at all. Why is she chatting on Facebook with her, This only gives her an impression he is insterested
