I was going out with a girl for a few months and I was happy with the way things were going and I think she was too. She told me she had cheated at a party. I didn’t really care cos the relationship was fairly casual and she wouldn’t want to hurt me. about a week later she said that she could’t make any commitment and wanted to break up. She seemed fairly upset about it

I seemed ok with it at the time but after a few months I’m thinking about her all the time and I’d love to be with her. What d’you think I should do?
