Chicki, I've never posted to you but did read this thread as best I could. Some random thoughts off the top of my head:
- This guy could be carrying STDs since he's been fooling around on you. (Condoms if you are using them aren't foolproof.) - If he's a control freak, this might be his way of weasling himself back into your life, especially (I don't know) if his OW dumped him. - Guys who mentally, verbally, emotionally, or physically abuse women are slick. This is a pretty quick turn-around for him to be "nice" and looking for reasons to come back. From my perspective, it looks like he thinks you are a pushover.
Nothing is wrong with you. However, this is just a few months after all of the troubles that I read about. You are "addicted" to this man...I don't mean that in a bad way because there are a number of biological and chemical reactions that happen when we bond with someone and fall in love with them that do cause a type of "withdrawal" when we end a relationship--these are part of being a human being. But you seem unable to break your need or want of him. You have to do that. You have to become emotionally and mentally strong. Has he been through counseling or therapy? Has he expressed remorse for the things he's done in the past? If not, then don't let him back.
That's just my two cents. I divorced a whack job who became an addict and became pretty verbally abusive. This is time to take care of you and to heal your heart and your soul.
