“I recently found out that my roommate cheated on his girlfriend with one of our co-workers. He did this two times!
When I confronted him about his unfaithfulness he was honest and forthcoming. He also told his girlfriend (who lives in another country) and she decided to stay with him and work things out.
However, he still hangs out with the “other woman” on a one-on-one basis and she comes over to the apartment and lies on his bed with him.
I told him this is wrong and unfair to his girlfriend. I don’t want to keep challenging him on this, but I’m not sure what else I can do. — Trying to Stay Loyal”
He’s not going to change so why waste your breath? Let him reap what he sows when and if his actual girlfriend returns. You’ve done the honorable thing already in confronting him yet he has kept on doing what he’s been doing. Stop trying.
You can always give this “other woman” the stink eye or glare at her whenever she is over. You could try that…but that’s not going to change anything. She’s just as bad as he is. He’s living in a burning house but hasn’t smelled the smoke or felt the heat. He’s oblivious and should be left to burn.
