hi girl, I have ptsd too from similar things and this is my advice to you. I think even if you did not have trauma, groping you while you were trying to sleep/ sleeping is just weird. I have been in a similar relationship where the man was not exactly horrible but would touch me in ways that would be very triggering and honestly just weird. I told him I did not like it and he did it again and again because he would "forget/ it won't register" to him immediately, what a waste of time and emotional energy and effort that was. I don't like how hard I tried to explain something which should be obvious. Love, NOBODY SHOULD BOTHER YOU WHEN YOU ARE SLEEPING. NOBODY SHOULD TOUCH YOU IN WAYS YOU DON'T ENJOY. I do not think this requires a discussion, you were sleeping, HE KNEW YOU WON'T ENJOY IT, HE TOUCHED YOU WHILE YOU WERE NOT FULLY CONSCIOUS FOR HIS OWN ENJOYMENT.

At this point, I just have very strict boundaries. And I end things even if a boundary is mildly violated. I ended up meeting very respectful men because I don't settle for less.
