What should I do? Is this assault?

I'm currently getting a divorce after 7 years of marriage and 2 kids together. I found out he'd been hiding things from me for nearly 4 years, he'd been sneaking money while we were broke to use on onlyfans to buy sexual content from local women, including some of my friends (he used a fake name and prepaid visa cards so it wouldn't show up on our bank statement) to me, what he did is cheating, and is a deal breaker. He has continued to lie to me since being caught, and has been mean to me which is very out of character for him, or at least I thought it was. He's just not the person I thought he was. We've been together for 10 years and I never thought he would do anything to hurt me.

After I asked for the divorce 2 weeks ago, he came over to see the kids while I sat in the bedroom. He came in the room and locked the door, and started to beg me to have sex with him just one more time. I said no, he held onto me and wouldn't let me go. He kept rubbing himself on me, trying to pull my robe off and get me to spread my legs, but I wouldn't let him and I started crying. He then started trying to kiss me, and I kept turning my head and covering my face, until he grabbed me by my hair and pulled my head back and smashed his mouth on mine. I started to kiss back, I guess out of habit, but only for a split second. I pushed his face away, and then he pushed me on the bed and climbed on top of me and again tried to pull off my robe. I kept saying no, kept telling him to stop, and kept trying to push him off. I probably said no at least 30 times, it took 2 hours to get him to let me out of the bedroom and I was terrified. He would let me up for a second but would end up back on me within seconds. I didn't want to scream or yell at him because I didn't want to scare my kids. The only thing that got him to stop touching me was me threatening to call the police, then he got mad and left, but not before asking me if I could send him more nudes 😒 I'm absolutely disgusted with him now. He apologized and said it wouldn't happen again, but I'm scared to even be in the same place as him now. I'm not sure if I should tell my lawyer what happened or if it's even assault because he did stop, but what he did really scared me and I didn't like it, at all. I have almost no family, no job, no car, and I'm already not sure what to do about all the legal stuff, and now this. I'm just so overwhelmed and scared.
