I have to agree with Brandnewday it's time to get a grip. I don't know the whole background but from what little I've read on this thread, you are being used BIGTIME. Oh and by the way, if there were a halter skimpy enough to make a WAW turn on the drop of a dime we would all be wearing them!
Your husband is a cake eater and a very screwed up one at that. Is there another woman involved? If there is you are taking one hell of a risk by continuing to sleep with him. Sleeping with him will not make him change his mind, but will leave you feeling used and abused.
The only thing that will give you your self respect back and at the sametime MAY get him to rethink his choices is for you to show him that your not the shrinking violet that he been used to dealing with. You are worth so much more!
When people come on here and tell you things you don't want to hear it's because they see you for what you truly are, not for the doormat your husband is making you out to be. Listen to them. Nothing, not even divorce, is worse then what you are living through now.
