I'm leaving my relationship and it's about to be ruined. Advice please!

So I am really trying to get my ducks in a row to leave my mentally, verbally, emotionally abusive relationship. I have my own bank account as well as a joint with him. I have been putting money into my own savings, buying things to move with our daughter, ect. My fiance is now saying he needs my bank account password so that we can go over money and stuff like that and see how much my checks are each month so he knows where each dollar is going. If he looks at my account, he will see everything I am trying to do but I dont know how to tell him no?

I can't move for another month and I am SO close to finally getting out and I'm so worried this is going to jeopardize everything. I work full time so this is MY money, but he wants to have control over it. He goes through all my statements and has done this many times in the past so I KNOW that is his main goal here....

Any advice is so appreciated because I dont know what to do!!
