PsySara, that's just bizarre that your husband hasn't taken any action. If he told you himself a while back that he doesn't want the marriage then you'd think he'd be actively participating in the divorce. When do you expect him to actually move out? When the divorce is finalized?
It really does sound like you've tried everything. It seems it's either divorce or endless years stuck in the same cycle and divorce may be harder in the short-term but it seems you are ready to move on and you have the confidence to know you do have a shot at meeting someone else if you ever wish. I hope this does pass quickly for you. Do you have anything planned for when the divorce is final, like a vacation?
