<human>: Give me the gist of the text in a nutshell

So things have been pretty shit for me in general. I've been suffering with anxiety/depression for a while now. 
Then the other day, a guy who I had been seeing for a few months and liked very much decided he couldn't cope with me any more and broke up with me.

So I was sad and crying and luckily I have lots of friends who are always there for me. 
So my friend came over and just listened to me and was lovely and stuff. 
I fell asleep in my pyjamas and he, fully clothed, next to me. And during the night I felt him grabbing at my breasts and stroking me and I froze up. He never seemed like the sort of person who would do something like that. 

I waited a while and decided to confront him and he was like "wait what" and basically claimed he was asleep and apologised profusely. 

I really want to believe him as he is so lovely most of the time and a close friend of mine. I told him it was okay and that I forgive him. 

Basically I just wanted to know how plausible it is that he would do that while unconscious? I also felt him kissing my back and stroking my forehead and I can't help but feel like he has broken my trust when I was most vulnerable.
<bot>: Friend came over to see me when I was really down. Groped me while I was seemingly asleep, claims to not have been awake while doing so.
