Is this normal? I feel bad about what I’m thinking.

My boyfriends friend (barely knows from what I know Bc he never mentioned of her until she got assaulted) got sexually assaulted weeks ago around the first week of school (August 26- September 2nd) at a bar and has been clinging to my boyfriend non-stop since . I rarely see my boyfriend like maybe when he comes home around 11 pm at night now then he gets up at work around 5am . I sound very selfish right now for thinking “I’m basically chopped liver”. I have not brought it up to him yet because I would like to hear all of your thoughts . I would like to bring it up to him but not sound rude about it. I’d get checking up on them for a bit just to make sure they are okay but I mean I just don’t understand.

I have not dealt with anyone who has been sexually assaulted. Is it normal for one to cling onto a person almost 24/7 ? Don’t get me wrong I have empathy for her and what happened . Sometimes I do get anxious of a personal situation that happened to my aunt. Her ex slept at his co-workers house Bc she was raped and left my aunt for his co worker. I’m probably overthinking the whole situation.
