Is my cheating father to blame for my inability to trust men?

I feel so bad for you! ); i think that you need to just stop and take a break. Don't automatically assume all men are bad. I know that there are bad men out there, but that doesn't mean they are all categorized as terrible and untrustworthy. Whenever you feel that way, just take a breath, think about all he's done for you, and as you breath out, let go of all your worries along with it. It sounds stupid, but it could help. Good luck and I hope you will be able to trust men a little bit more now.
