Trying to detach

[HeadUp]

So I looked at our bank statement and the W has over drawn the account again. Now I am paying the bills and rent at the house so my children have a place to stay. The W doesn't work. I have been told by people to open my own account and give her checks for what she needs for the house and nothing more. I feel doing this is going to infuriate her and make my chances slimmer. But I can't move forward when out of my check I by gas once and that is all the cash I spend while she is out having a good time spending it all over the place. Am I being petty or do I have a point?
