What if....you talk to your L about filing with some caveats. He gets what he wants but he has to make some concessions to you. First of all, no more whore at exchanges. It's too much for you and your S right now. Also, no more S at any dr appt. Inappropriate. No more badgering you with emails and texts. If he has something to say, one email. You get one day to read and reply.
What else would help you get some power back? You've been letting him call all the shots. Time to call some of your own. I'm sure that some of the others can help make a list to take to your L.
