Advice/ reassurance about possible Sexual Assault

Hi,

I'm struggling at the moment to fully understand what I went through during the relationship I ended. It ended out toxic with him being drunk pretty much all the time and making me feel uncomfortable.

Getting to the point.. before the drinking started we had made sure we knew eachothers boundaries and had consented to being able to wake eachother up sexually occasionally.

Skipping forward to drunk period. I had gone to bed and woke up because I found he had initiated sex while I was asleep. This didn't usually bother me as we said we would make sure we wake up before carrying on but I knew his intentions from what he was whispering to himself and how he was acting that he didn't mean to wake me up and he didn't know I was. Him being drunk, I felt physically sick. I felt so uncomfortable but I just couldn't get out the words to stop him. This happened a few nights with him drunk.

I never said anything and it didn't happen again and i ended up leaving due to the drink.

Over a year since leaving and I can't get those moments out my head and its really playing with my mental health. My therapist says she won't say if it's classed as SA or not ( leaving it up to me) but I don't want to tell people I know because I know accusing someone of something like that is awful and I don't want sympathy or for people to feel sorry for me.

I feel like it's wrong but I did give him consent when we first moved in together.

Apologies for the long post. I don't want sympathy. Any opinions would be appreciated.
