My parents divorced when I was a child, I am now early 30s. When I was 16 they got back together then broke up twice more in the space of a few years.
In my 20s I moved abroad and they grew closer. My dad had a near death experience and my mum cared for him and his ailing parent as though they were still married. Other than that I never really knew if it was just romance or friendship. But they went on holidays, theatre trips, concerts etc.
The result is they relied heavily on each other and now my dad suddenly has a new partner. My mum has been ditched and now he is holidaying, going to events with this woman. When I broke the news to my mum she cried and got angry...
Now he is asking me to go to a concert in his place with her that theyve had planned for a year as he 'can't' do things with her anymore. I've told him no, he needs to address this with her, AIBU?
