Awww, well, I understand your frustrations, but I can't help feeling a little sorry for your wife. Sounds like she needed some serious therapy especially after her mother died, and I don't know how obvious you made it, but the fact you didn't really love her might have had an effect on her too. It's a sad situation for everyone involved. I hope your children will be okay and both you and your wife can finally find some peace in the future.
