After reading your post I could deduce that both of you have outgrown each other and there is only a single solution for you. I have recently decided to take the steps to go separate ways with my wife who I cannot remember when was the last time I spent 2 hours in the same room and she did not attack me with her forked tongue.

I suggest you sort out the legal aspects of your relationship by consulting with a lawyer who specialises in the area of family law.
