Enter the legal process and both of you will pay money. Positions will be taken and it will simply get out of hand.
Just reading your note - you may be frustrated but this is not a very respectful review of 'she' - presumably your long suffering wife.
If you have money either waste it on legal or:
- take a long look at this. Mediation with somebody who can tell both of you some (unpleasant) observations about yourselves would be instructive.
Your lawyer will act in your interest, but where (s)he cautions you about actions it will be a whisper.
If it is beyond repair - maybe it is - getting both sides to be reasonable is the key. The trouble is each partners view of their own reasonable behaviour is not seen the same way by the other - in short go get counselling together as a start with an open mind. [Stay strapped to the seat.]
