My husband raped me

That sounds crazy. How could a husband rape his wife? I though it was consensual once you say I do. It’s not. You can still say no. We went out on a date night. The first time since our LO of 3 months is born. We went out to a fancy restaurant. I haven’t had a drink in over a year, so I’m enjoyed myself. Unfortunately I had to much to drink... I was pretty much blacked out but I do remember saying no, stop 2 times. I just don’t know what to do. This isn’t the first time I’ve waken up naked and not remembered the night before. I just need advice. We have 2 kids together.
