This reminds me of a book I read, called Are You the One for Me? In it, the author points out that we tend to seek in a partner the same traits that caused us hurt in our childhood. It's usually the opposite-gender parent. We seek the same problematic personality type (alcoholic, workaholic, abuser, whatever) because we are still constantly striving to finally win the love, approval, devotion, whatever, of that parent type. Deep down, we feel that if we can get that from someone like that parent type, we will be able to fill the void.
But it doesn't work.
This is, I suspect, why you have *always* been lied to, cheated on, etc. It's no coincidence. And it's not that all people are like that. You just keep going back to the same type of person (friends, bosses, etc. - not just romantic interests). It's not that you *want* to be treated badly. It's that there is some common trait shared by these types of people that remind you of your dad (or mom). Maybe your dad left your mom, cheated on her, or was in some other way emotionally unavailable to you. On some level, you have felt that if you could get that type of friend to be decent toward you, or guy to stay with you, you could forever actually feel secure, because you have won the loyalty of even that kind of guy.
Maybe.
It's just a thought.
Anyway, this isn't something that I think any of us moms can really help you fix. I mean, we can share our experiences, our theories, whatever, but this is something you need to work on in therapy.
Please, please, please decide that you're going to do it! And tell your husband that you're making this commitment, and ask him to join you for at least a few sessions. This fresh start might be the single thing you two need.
Good luck.
