Is this sexual assault?

UPDATE #2

I asked for a divorce and he agreed, it's been a long time coming but this was the last straw. I'm finally leaving a narcissist asshole who doesn't appreciate me.

**update**

My husband is now saying that he did not hear me say no, so he did it anyways. And that it was okay because he was horny.

My husband 6 months ago came home drunk and high. I was asleep and he woke me up for sex. I said no. I was half way asleep when he took one hand and grabbed my ass and the other hand grabbed my boobs (I was lying on my side) he then proceeded to hump me, then he pulled me in tighter and humped faster and I woke up from the movement. He finished and rolled over. Today while napping together on the sofa before I go to my parents for Thanksgiving, he did the SAME thing. He was horny and asked if he could dry hump me. I said no. Then I again, was half way asleep and proceeded to hump my ass and grip my waist. I didn't even know what to do I was frozen. (In my past I worked at a local ice cream shop and a male coworker locked me in the freezer with me and he began to kiss me and grab me and I felt frozen especially in the freezer. I ended up quitting and no one knew) this felt a lot like that.. I don't know what to say or do about this..
