Aver, you are making progress dealing with this house situation! Way to get the ball rolling. My opinions:

1) intervention would be waste of time...possibly make X defensive, resentful and fight harder for the house.

2)Do you REALLY want to waste tons of money, stress, and time going to court for the house? I know it would be horrible if OW moved in but I think when you detach you won't care. Honestly!
