What should i do?

Kayla

A few weeks ago my friend had texted me saying that a girl in her class was talking my boyfriend and had said that the girl she works with had told her that while they dated him he would rape her in her sleep and If she woke up and told him no he wouldn’t stop. I brought it up to him and he denied that it ever happened and got mad at me for even asking about it. I feel like i should message her and ask because if it’s true that’s not someone i want to date to. I’ve dealt with sexual assaults and i just don’t want to go through it again. But i just don’t know how to come across it with her
