A year ago I helped pay for a trip to europe for my ex as a graduation present. She broke up with me two weeks after she came back. She said she needed space and had been thinking about it for a couple months but she thought the feelings would pass. Before we broke up she asked for more space to do her own thing and I gave it to her. She was hanging out on a boat with people from work and I suspected there might be something going on. She then broke up with me and insisted it had nothing to do with feeling for someone else but that she just didn't want a bf because she had so much she wanted to do on her own. Of course my gut feeling was right and she was staying at one of the guys house a day after we broke up. After that I refused to talk to her and told that I wanted nothing to do with her. She believed she had done nothing wrong and insisted she never cheated. She cried to me and said I hurt so much and that I ruined her and I was wrong.

Now its a year later and she is having some troubles in her life and says she really needs me as a friend and misses me. She has also said she hasn't ruled out the two of us getting back together but doesn't want to tug me along. She said she is going overseas for awhile and wants to be friends before she goes. What should I do and why does she insist on being friends?
