Not sure need advice asap.

So me and the hubby have been together almost 3 years. This is personal but last night I had a headache and just wanted to sleep. I told him goodnight love him and rolled over. Well five minutes passed and as I'm going to sleep he proceeds to pull my panties down and have sex with me. I didn't move or anything and halfway through he stops and asks if I'm okay. I told him no what he did was wrong. We talked about it but I'm not sure where to go from here. I feel disgusted and I never thought he would do that. Advice please?
