Been with DP for 5 years, lived together for 2. DP and I went on holiday in a different part of the country. At a shop there was a woman who had lived in the same country that DP is originally from.
Unknown to me at the time, DP had got this womans number and had started texting her after we got back home. Pretty much straight away in his messages, he had been telling her bad points about our relationship and sex life. The woman said she wasn't interested in anything more than friends with him after he said this (she obviously assumed he was saying it for a reason as he jumped into that topic so quickly). She then stopped replying to his messages as she must have been very uncomfortable/awkward with what he was saying.
When I saw the texts I said it's totally inappropriate and has hurt me etc, DP thinks that it's fine and normal as he "needed to vent to someone" - I said why a random woman that you barely knew? I don't want my dirty laundry airing to practical strangers!!
We're due to go back to that location on holiday again soon and I am feeling very uncomfortable to be around where that woman might be again. DP thinks its fine and he doesn't understand why I'm reacting like this
AIBU to think that what he did was fucking weird and inappropriate?
