My partner (who I’ve been with for just under a year, but have known through work for quite a few years) is part of a group on Facebook/Twitter/instagram where they all have the same type of Labrador cross dog. Quite a few of them have dogs from the same litter- he has known these women longer than he has known me. They have meet-ups where they walk the dogs together- these are often hours away from where we live as they are all spread out across the uk. They are having one next month that my partner had taken the day off work to go to. However I have a medical appointment on the same day that my partner wants to come with me (I have a chronic health condition and am slightly hard of hearing so he wants to be there for support) so he has told the group that he can’t go. They are really upset that he’s not going and are saying that I’m taking him away from his friends and that they’re all travelling for hours (one woman is driving for 10 and a half hours for this walk) and that I could easily change an appointment. They feel that I’m jealous of the bond that they all have and that I’m splitting up their ‘family’ with the dogs. I am absolutely stunned by their reaction and think it is really odd. AIBU or should I encourage him to go? I’m really confused by all of this
