dh told me that a group of his colleagues were going to go and watch the motor racing at the weekend and asked if I minded him going too. Of course I said I didn't. Then, later, he apologised for not inviting me and asked if I wanted to go. I do like motor racing but we couldn't take dd (she would freak out at the noise) so I said no as I'd rather not abandon her for the only full day I get her in the week. Then he tells me he's invited my (gorgeous single) best friend along. (he's gone to races with her before and I haven't had a problem with it) The other guys going are taking their partners along. They have never met me as he's only been in the job a couple of months.
AIBU to not want him to take her? It will cause a fuss if I put my foot down on this, But it feels like a couples thing to me (obviously not to him) and I'm gutted that he's invited her.
