Affair discovered 2

[STH17]

Well I was all set to go to the local bank today to close a joint checking account we hardly use and only has $50 in it, then open a checking account for myself there. It's the same bank the mortgage is with (which is in my name only). Then I thought I could transfer the money from our other joint savings and checking accounts into the new one I make for myself, leaving W to handle making payments on the joint credit card that she is primary owner of.

So is that all just petty or would it actually be a bit of a reality check still for W? At the very least I think I should open an account for myself so I can have something I feel in control of. That's what I would really want in a marriage going forward anyway.

Are these things I should talk to W about? We agreed to separate accounts on Monday, but I feel like she is backing out of that agreement. She also said she wants to be fair, but nothing about her past spending has been fair during our marriage.

Bottom line is I don't want to share accounts with someone who doesn't want to share any other part of my life. Can I tell her that?
