Ex and I split at the beginning of the year (her decision - OW) and I stayed in the house with de facto main caring responsibilities for our shared dog - bought together 4 years ago.
She continued seeing him on the days I was working full time, and seemed keen about this - it was one of the things that she checked upon splitting up, that she would still get to see the dog. I also asked her to take care of him when I've been holiday, which she has. When we've both been away separately I've arranged kennels.
Now that the house sale has been sorted out (I bought her out) she has decided that she doesn't want to see him anymore - that it is a ongoing tie that doesn't benefit us. Which I get, but I want best care for my dog, and she is able to do that far better than someone he doesn't know - he is a difficult dog unfortunately, reactive and I worry about him with others, but she knows how he is obviously and how to manage him.
We have a dog walker that can see him on Mondays and Tuesdays, which I will pay for now, and I am around Weds and Thursdays, but Fridays are still an issue and holidays are still an issue, and I am miffed that she won't step up and take responsibility on these occasions because that is in his best interests - best for his welfare and quality of life.
AIBU to have this expectation that she continues to try to look after him on occasions that I can't? Given that he is a joint responsibility , we both committed to getting him, and he has some behavioural issues that mean he is best with someone who knows him well. (And yes, we have worked hard and continue to work hard on his behaviour, with trainers, classes and books, - he has guarding tendencies and can also be unpredicatbly reactive at times)
