I can't believe that this happened. It's like a bad film cliche. But last night when DH and I were having sex, he said my sister's name!
I know it sounds like something out of EastEnders but it genuinely happened, and I have had a sleepless night as a result.
I challenged him on it, and then that made it worse because at first he denied it and then said it was a joke.
I thought our marriage was fine. I love my sister. I have a good relationship with her (I think). There has never been any suspicion of my DH in any way let alone with her.
I have changed my name for this thread because I know she uses Mumsnet sometimes. I don't know what to do. It could genuinely have been a joke of his. Or, horribly, a fantasy of some kind. Or obviously the worst possible scenario (which would ruin my life).
Should I mention it to my sister? Mention it to him again? Let it drop?
