You can agree to give her X amount per month and Venmo it into her account, her own account that has no ties to you. That is what she gets and not a penny more.
Trust me you do not want to know what she is doing. Joint accounts also show your afraid and scared to let go.
I would also advise to not move out. If I had moved out of my house my XW would have been bringing guys over immediately into our home when I was with our daughters in my apartment. SMH.
