Me and this girl have been seeing each other and been heavily talking. Her last boyfriend was terrible to her and didn't treat her good so they broke up, but it was always off and on. We later then started talking and seeing each other and she told me that she was done with him and that she didn't want to get back together again because it always ended up hurting her. We both like each other but she said she just needs some time as she doesn't want to get hurt again. A couple months down we are still talking but one time I saw her recently snap chatting her ex boyfriend. It really bothered me and made me madbut she told me nothing was happening between them at all. What should I do?
