I really do want to clarify my thoughts and sort of expand on what whatis has said. If you do choose to separate or file for D or take a sabbatical to Europe to escape the drama, do it from a position of strength and from recongizing what it is that YOU want. Do not do it in an effort to control or manipulate the situation. I want to clarify this because in the past, I've seen many of your posts where you seem to indicate that (e.g., she won't go to marriage counseling, so now I'm gonna divorce her). You cannot control the sitch as evidenced by the fact that its getting out of control. Step back and rise above the every day drama.
