but she doesnt want to listen or change.
Has it occurred to you that YOU don't want to listen or change ?
My advice is explain to her that if she "forces you" to move to Poland you will which will be her loss financially.
Do not let the kids be used as a weapon of pity because children are resilient and adjust quickly.
Her on the other hand will be "forced" to lower her standards to the poverty level and her, not like a child, will find it very difficult to adjust to.
Let her decide to make her own life miserable by not allowing her to use you. (Divorce will follow shortly when you cut her off financially)
Keep her as broke as possible until she divorces you IN POLAND when the merry go round starts to slow down.
Bide your time until your children are old enough to make a legal choice of who they want to live with, divorce the unreasonable woman (if she hasn't already divorced you first) when they become of that age, move back to the UK with or without your grown children, find a few much younger women to date on the "catch and release" plan and FINALLY you will have YOUR life back.
Chalk it up to the nature of the beasts and your own poor judgment.
Now do you understand why so many guys are becoming gay ?
It's all the feminist movements fault.
