There has been a lot of tension between my girlfriend, myself, and my (now former) room-mate.
When I moved in with him (and slightly further away from my girlfriend), my girlfriend was sort-of upset, but not terribly. She had a phone conversation with him and said, jokingly, "I thought we were friends!" He took it literally and was upset for about 2 months while saying nothing. He later informed me that he really dislikes her, didn't want her in the room, et cetera.
Things went back and forth between them. They both have different stories of their interactions. I tried to remain neutral instead of taking sides because I didn't know what was said between them. My girlfriend took offense and claimed that I wasn't sticking up for her as I should be.
After about a month or two of tense feelings, I finally said enough and told my room-mate he was an . I found out through many other people that he talked about her (and me) behind our backs.
My girlfriend claims this attempt on my part to make right of the situation came too late and wasn't good enough.
Now, 2 months after I moved away from my room-mate, she wants me to call him up and tell him he was an again to prove that I believe her side of the story. My room-mate just wants to drop the entire issue (his words from the last time we spoke).
I sort-of understand where my girl is coming from, but I don't feel like re-kindling harsh feelings as they could have repercussions next year (I am living with someone who is a friend of my room-mate, and I know he talks to him, probably about me).
What should I do?
