I broke up with my girlfriend 4 months ago and I still really miss her, I think about her all the time but we are in different countries right now. The reason I broke up with her was because I needed more space from the relationship and I was doing an internship abroad but things between us got sour because she never really understood the reason why I left. Now as more time has passed I find myself more alone and wanting her back. She started dating a "friend" of mine and that has made my situation worse, I feel that I should have never broken up with her and I can't stand the idea that she is with someone else. Any thoughts on what I should do?
