My boyfriend told me that he slept with one of his good friends who is a married woman for a few weeks just before we got together, and that they’re ‘good friends’ now and are planning to meet up soon when she’s back in the country. Her husband still doesn’t know and she doesn’t plan on telling him.
I told my boyfriend that I’m not comfortable with this morally and that I think he should be firm with her that this is wrong and that she needs to tell her husband, and if she keeps refusing to do so that he should tell her husband as a last resort and also cut all ties with her. He says that he can’t do all that.
Am I being unreasonable?
