Will try to keep it concise.
Had an extramarital affair 15 years ago. Still in touch. Differences in everything make any contact now mainly acrimonious but still in touch.
Had always said I look after their dog if anything happened. They had a brain haemorrhage 2 years ago. I took the dog. They survived & made a good recovery. Dog went back. Just been texted saying should anything happen they’d now rather dog went to another person. Apparently as I was stressed when I had it the last time. And also because I apparently said I’d get their dog put down rather than rehome it. I may have said this from the point of view it an old dog & very fixated on person who owns it has it is a single person household & they are all they’ve known. And I would have said it in the context that if I could not look after it I would not rehome it as I have seen it’s separation anxiety. It’s distressing & it knows me & my dogs.
AIBU to be offended & hurt by this two years after the event & after I did everything to keep it safe & happy the last time. I did a LOT not just with the dog but with person visiting them daily, buying clothes & food. Taking them home & being on call while they recovered etc.
