So I had just recently in November started dating one of my best friends. He was happy and so was I. we dated for three monthsand I fell in love with my best friend. But his ex girlfriend was always around. (they were on swim team together) and he graduates this year with her and he had dated her for two years before me and then in November we were so happy until January he started acting up and one day he told me his dad wanted us to break up because of his mission (which we usually got ove and moved on because his dad said this every week) but this time he really meant it and we broke up and I felt so bad I tried to hurt myself. A week later I found out he was taking his ex on a date. This broke my heart. She had always texted him and was always talking to him but he said he was over her and I made him happy. But then he breaks up with me and told me one day that he honestly still loved his ex girlfriend and he never planned on doing this to me and all I want is him back. I have to see her and him together every day because were still "best friends" She makes him miserable, he never smiles or is happy but he "loves her" but I'm hurt and I was so happy and all I've been is miserable. W eboth have been just miserable. Seeing as how him and his ex would always argue when they dated and break up and get back together and break up, I don't know if I should completely give up on him, yes he will be gone for two years on his mission but all I could ever ask for is for him to realize I love him. And I just don't know what to do anymore. I don't want to let go. All I want is my best friend. I don't know if I should wait until after his mission or if he will ever realize she doesn't make him happy and I do. Will he ever get over her?

You need to get over him. He is with this girl because he wants to be. Grasp that and let him go.
