Am I being crazy?

Are you guys comfortable with your man being friends with a woman who has cheated before in her relationship? I feel a bit awkward with this one girl who has openly cheated... she’s friends with my boyfriend and I but more his friend than mine. I don’t really trust her because if she couldn’t respect her own relationship.. why would she respect mine..?

I trust my boyfriend so much, I know he wouldn’t put me in a position to get hurt but personally I just don’t feel right with her sending him memes or dming him or sending him snaps they’re innocent but maybe I’m being crazy & overthinking?
