Am I right to be upset??

So, to make a long story short, I told my husband a little over a week ago that we are over and I want a divorce. He is manipulative and emotionally abusive and I finally snapped after he accused me of cheating on him for only the 1000th time in our relationship. I have never cheated and never would, but he is extremely insecure and always thinks the worst of me.

So since I have told him I want a divorce I have consulted with an attorney and found out I’m going to need time to get some money together and have a good exit plan. I have 5 kids, 2 are with him, and since I’ve told him that I want a divorce he immediately told me to take all 5 of my kids and move out, (even though it was my house that I bought before we got married and I pay for it from my own account and always have) and also told me I need to sign a paper to get my 3 kids that are not his off his health insurance, even though he pays the exact same for health insurance whether he has one kid on or ten. I told him I’m happy to move out if he buys out my interest in the house but I’m not agreeing to take my kids off his healthcare until the divorce is final.

Since I need time to get my ducks in a row and I don’t want the environment at home to be toxic for the kids while we are separating, I told my husband I’d give him 3 months to show significant changes, but really I’m not anticipating him changing much and I’m using this time to get ready to leave. Well in the last week and a half he has cooked more and helped more with the kids and housework, but he has still questioned if I want someone else, and the other night apparently went and got a Tarot card reading and whoever did that reading also told him I was cheating, according to him. Well I decided to stop sleeping with him because emotionally I just can’t take it even though he has been pressuring me for sex every day since I said I wanted the divorce. I gave in initially but last night I flat out said I wasn’t interested and I didn’t appreciate the way he was asking, like I owed it to him or something, and he got mad, said he was “just going to jerk off” then went to the bathroom and slammed and locked the door.

All in all his behavior has only upset me more, and I feel like even though he has helped more at home, the core issues like jealousy and entitlement are still there. He begs me to not leave him but then gets mad when I enforce boundaries, and still doesn’t show trust or respect for me. Am I assessing this right? I need to just get out but I’m trying to avoid spending tons of money on attorneys. Any advice is appreciated.
