My crush (whome I proposed) likes my roommate.....

So in college I have crush but she likes my roommate btw roommate is not good looking just a average guy but he talks to girls in very different way like every other girl is attracted to him..... So few days ago my crush asked him can they come in relationship that time he said kinda yes but later said no. I have proposed my crush and now she just says that she is moving on ,she had attachment issues, and stuff. Which is making me frustrated. It's heavy for me to process. And I just sometimes feel that my crush doesn't want to moveon. As reply to my proposal she said she is not ready to date anyone 😭 she considers me as good friend. .y roomate said thet he is ignoring her but she is the one who chase him.... Roomate is bad guy like he just wants to use her.... Passes bad comment about her when he is with his friends. It's hurting me now
