Me and my ex-boyfriend broke up about 4 months ago and a couple weeks after the breakup he told me that he was cheating and he has been with some girl for about a year. Then when we got to school he dated some new girl and then broke up with her about 2 weeks later. I miss him and want to make it right and start over. Should I try to go out with him again and start over or should I forget about him? Also if I should get back with him ( how do I get back with him)?
