He said my sister's name

[Zebrabottle]

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?

Im not following your every post. Don't flatter yourself

Never say never!!!!! There is always time to learn and grow 😆

The comments on this thread are mad.

I once called my friend Lorraine by mistake. Does this mean I secretly long for Lorraine (I don’t know anyone by that name, so no) - or was my brain being random & weird?

My husband’s mum recently called me by his ex-wife’s name - even though we’ve been together for 20 years. She was mortified but I know she didn’t mean anything by it.

Sometimes our brains do their own thing!

Is your sister younger and better looking than you?
if she is then you know the answer already. if she's not it may have been a sick joke. Either way it doesn't say much for your DH.

My legs would remain firmly closed here on out. Ducks in a row then I'm off.

I think this too.

Do you look like your sister?
