You made the right decision Anajdlee.
Your ex-boyfriend clearly didn't know what he wanted in life in terms of a relationship, he's obviously very confused about his sexuality; dating a woman while having sex with men?
Anyway, good luck in the future. I imagine an experience like this might really mess you up and make you very suspicious of any future boyfriends you may have. But don't worry, you'll find a man deserving of you soon enough, one who doesn't have any nasty skeletons in his closet.
