Between the 2 choices, living in the frying pan or falling into the fire. Neither are choices that your gonna be happy with anyways. One will bring 24/7 misery, still no respect, love, or true interaction with a loving wife. The 2nd, will hurt still, with all the same above missing but bring some closure, protect you and your kids.
I'm sorry you have to decide. I think you know what your thinking, and i'll support whatever you need/want to do.
Good luck, keep venting!! you do have people listening and support you.
