Coping with Bi-Polar WAW

[CountingCrows]

When I told her that I was changing the locks on the house, she attacked me for taking away the only chance for her to see s7 except at night after she got off work...a supervised visit on my terms only. I'm not at all trying to keep s7 from having a relationship, I relented and allow her over in the mornings. But I have to go to work before s7 gets on the bus, which is why she was coming over in the a.m. I can change my schedule to allow me to leave after he gets on the bus, though.

At what point to I demand a decision be made between him or me? I don't feel that I can use the loss of visits in the morning as a consequence for her decision to keep OM in her life. I don't want to use s7 as a pawn in this game.

What's the other option. Choose to get rid of OM or I'll file for divorce?
