ok pf, this is strictly a question from my cousin. he has been going out with a girl for about 1 year and a half. they broke up once after about 5 months because he joined the military and while he was gone she cheated on him. he came home and took her back. they got engaged about 3 months after they got back together. about 8 months later she broke up with him again and called off the engagement(almost completely sure cheating wasnt involved). they stayed broke up for two months and are now back together. everything is going great between them so far. he loves the girl a lot and she seems to have changed. tips and opinions on what he should think or if they have a fighting chance of staying together.?
