My cousin and boyfriend(ex)

If my boyfriend that I was with 4 2 years cheated on me 3 times and once with my own cousin...do you think I should take him back...and become back friends with my cousin. ? Because I strongly dislike both=/

Never take him back. As far as your cousin goes, family is family. For now, treat her like the backstabber that she is, but you might just find yourself forgiving her later in life.

Well no one can make that decision. only you. With your boyfriend my opinion is his so not worth it. You deserve better and chances are he'll do it to you again... have you ever asked him why he keesp cheating? Maybe if you got down to the bottom of it as to why he keeps doing it maybe you could help him then in time give things ago...If he loves you he should acceot what ever decision you make. He can't expect you to trust him and take him back straight away. He has to earn your trust and respect again, because with no trust there is no communication and no relationship.
Tell him exactly how you feel and what you want. Then work something out with him, only do this though if you really love him and want to be with him.
As for your cousin, I wouldn't blame you if you never wanted to see or speak to them again. But as someone said before she is family, but that doesnt mean she has a right to do something like that and get away with it. Maybe for now dont communicate with her, if you see her be plesant but dont go out of your way for her.
I wish you the best of luck.
