Sexual abuse trigger warning ‼️

I suffer from anxiety and depression on a day to day basis but have had it under control for a bit now. I also have ptsd from being sexually abused by a family friend when I was younger. I never told anyone until I became an adult and went to therapy. Well a few years have passed and I was doing fine. I met my now husband and am expecting my first child. Everything seemed great until tonight. My husband was in the mood but I wasn’t because I’m 7 months and uncomfortable. Well I turned to face away from him and he sort of big spooned me. I was fine with that and I said, “I’m sorry but I just don’t feel like it tonight.” He would always leave it at that and just fall asleep with me but tonight he just thrusted a little against me. I froze, went limp, and started tearing up. I couldn’t make a sound for a solid minute and then I got up to go to the restroom as a safe space. He came to the door and asked if I was okay and if I was mad at him. I just said no and that I needed to take my prenatal medicine. It’s been an hour now and he fell asleep but I couldn’t stop crying and shaking for a while. It’s like that moment sent me straight to being in a room in the dark while being touched by a man that I was supposed to trust. I know my husband didn’t mean to make me feel this way but I felt so weak and scared. This is the only time in our relationship that I’ve felt like this.
