Most Helpful Girl
He's scared that he will break your heart because he probably know he's no good for a good person like you, You're right about leaving him if he says ''I don't know'' in my opinion, the answer should be simple yes or no. He might be sad and cry when you leave but that doesn't change the fact that he cheated on you two months into the relationship you two shared. Everyone will tell you to leave him because he cheated which might be the best thing to do because they say once a cheater always a cheater but you have to follow your heart and it's probably confusing. Give it some time.
