The only reason I keep in contact with my estranged wife is because I am determined to set her back as far as?

I imagine you know this answer is coming. The best form of revenge is sucess. Old pieces of wisdom don't become common phrases for nothing. It's learned wisdom that is true. Revenge is only sweet very temporarily an then it feels hollow quite quickly. You should concentrate on your own happiness and success and leave her to drive her own life. If she has wronged you trust in karma. If you do bad things for bad reasons ie revenge then bad things will come to you in the smallest of ways or the biggest. Even now your angry bitter thoughts are probably hurting you more than helping you. Cut her off and then you won't know and slowly won't care what she has or is doing.

What do you benefit by setting her back? All you're doing is holding yourself down with her. Let go of the hatred and find your happiness. The best revenge would be to live a successful life and to be happy. You're going to be stuck and unable to move forward if you insist on trying to drag her down.

take the kids and you'll get the house and CS at work Manu female co-workers more with the change of the laws are paying ex- husbands CS I'd say 1/3 of them - that's where a woman is hurt

And just how is that working out for you?
