I think my husband touches me at night

Hello , as the title says , I think my husband m(35) is touching me at night (f25) . Last year when I was sleeping I woke up to my husband touching my breasts and body when I woke up he got up and went to the bathroom and the next day he said he was comforting me because he thought I had a bad dream because I was talking in my sleep . So I just brushed it off I thought maybe I was talking and I was freaking him out so maybe he was or was not comforting me . So recently a week ago I woke up with bruise on my ass cheek. I don’t remember him touching me and he works a physically draining job so I don’t know how he even has the energy to do this . Now that this bruise is almost faded but still there ,today, I wake up with another bruise and this one actually hurts when you touch it and the craziest thing is it’s almost in the same spot . I don’t understand how I’m not waking up through this . I don’t even know I’m so confused and I want to confront him when he gets home from work . Has this happened to any of you and what made you realize that you were right ?? Please I would like to know
