Hi- name change for obvious reasons.
I will try to keep this brief.
I have evidence that my controlling H of 14 years has been cheating for the best part of 14 years 
I’m so sad about it but after a weekend of feeling sorry for myself I now need to plan.
How do I avoid being screwed over like my SIL was when she left the family (BH has law and accountancy specialists in the family who helped BIL dodge paying a LOT and she’s now in a bad way financially and emotionally)
I’m wondering about drawing out all of our savings as I fear he will cut us off to gain controls when I end the marriage.
Any ideas would be greatly appreciated to protect me and the DC
