I [M] Fucked my roommate [F]

For more or less, I’ve been going through a lot this last year. I’ve been struggling with depression and trying to learn to be okay on my own/not in a relationship. A girl I went to school with in another state moved to the same state as me for work, and I honestly love her. But, she is dating another guy we went to school with. I’m incredibly happy for both of them, as he has been wanting this for a long time and they deserve each other. The reason I’m writing this is because not feeling like I’m date-able/lovable has been putting me into positions where I make regrettable choices and risk other people’s relationships. AKA: My roommate.
