<human>: So this situation is extremely complicated, but i'll try to summarize it. Me and my ex used to be best friends and we eventually dated. Then she broke up with me, but although not technically dating we were still "together" (We were working on the problems in our relationship). Then she started flirting with another guy behind my back. One day we got in a huge argument and said we were officially over. Then later she started to go out with other said guy. But whenever we would talk/hangout we would always act the way we did when we were together. The problem is I kept getting hurt and confused because she has a boyfriend, but treats me like one too. Then today she told me that she loves me, but loves him too. She knows that it is wrong and therefore she is going to choose one of us. What should I do?????? I love her so much and she said that if she could go back she would fix all she did wrong. I've forgiven her and am confident that she would be a good girlfriend if she ends up picking me. Is there anything I can do about this? I really want her to pick me.
P.s. We're in our late teens and she has matured and changed a lot from the time we started going out up to today.
