(((Emmy))) - you didn't come here because things were great between you and him. I could get lost in the "but we had some really good times!!!!", totally forgetting the bad.
I had to make a list of things he did that hurt me, that made me not trust him. I read over that list every time I got the "but....." thoughts.
Why not wait and see if his actions meet his words? No binges. Letting you have the debit card when you don't do what he wants.
Though I know how hard it is, there's nothing wrong with saying "I need more time". This is YOUR life and your kids. I suggest you give him a chance to prove his words, and keep taking care of you and your kids.
Hugs and prayers,
Amy
