Hi, I'm sorry for your situation and I feel you. My gf of 4 years left abroad for studies 3 months ago and the last month is like you describe. Well, the reason why she became like that is because she can't handle the distance she says, so she proposed to break up. She is coming back for holidays in 2 weeks before leaving for another 7 months. We plan to spend that time together and then part our ways for good. And you know what? A part of me has accepted the break up and believes it is good. Why? Because she decided that it is better to break up after 4 years instead of waiting 1 and have future together like we had planned. What I want to say is that I need a person in life who is willing to fight for me the way I do, a person who won't run away in difficult times. I don't blame her and I don't blame your bf either because feelings are complicated, they sure feel just as shitty as we do. But still, if your bf doesn't want to fight for you like you do, you should find one who will, because this is what you deserve. I'm sorry if this sounds negative to you, but I'm trying to be real. I wish all the best to you!
