SA? Needing help

Trigger Warning…..

So this happen a couple months ago and I’m trying to see if this qualifies as SA cause this has never happen to me and not sure what steps to take. (I’ll be calling the man that did this to me John Doe and his wife Amber) so this happen when I went over to a house that my brother and SIL were house sitting for cause they had a pool and we went over with permission from the owner to swim there. So they invited me, my other brother and my SIL sister (Amber) which is John doe’s wife. Everyone was drinking but me, it was getting late so amber went home and John stayed up with everyone else. I got out of the pool, showered and went upstairs to sleep in the smallest room to leave the larger ones for everyone else. All I was wearing was a night gown nothing underneath cause I didn’t pack clothes. Well I fell asleep and John Doe got in my bed while I was asleep, pulled me under his blanket got in mine and put his hands under my Dress touched my breast and was about to touch my flower and that’s when I woke up. I got up left crying and scared didn’t know what to do so I called all the girls there and got no answer, I didn’t want to wake everyone so I went to another empty room texted everyone where I was and waited it out. I didn’t report it after because I was scared but his wife Amber called her sister , my SIL apologizing for what he did and used the excuse that he was drunk. It’s been eating at me thinking about it making me uncomfortable and I don’t know how to take what happen to me cause I was sleeping and was not able to give consent in anyway. And I blame myself for being so stupid and not being more careful and more alert of people
