It was a very difficult situation when ES's wife fell out with her parents. She'd not had the easiest of childhood's, they could be very difficult and their relationship was, shall we say rather toxic. Our ES was furious with what had happened in the months leading up to the wedding. I was very concerned that by excluding them, the relationship could be permanently damaged.
She had made a couple of calls to Mr. S., running her daughter down which at the time we found very hard to take, that said, the things she was saying turned out to be true resulting in our estrangement with our son
although we didn't believe them at the time.
We stopped contacting them and they us. There was a wedding blessing here in the UK a few months after the wedding and her parents were there but we each kept our distance.
When our eldest GC was Christened, ES's wife asked if we would mind her parents sitting with us in the church. The pew had a large card on it saying 'For the GP's' and we said of course it would be OK.
It was a little awkward to begin with but by the time the service was over and we went to the 'do' things were OK but our ES's animosity toward his parents' in law continued it seems up until the time we were cut out.
Her parents divorced some time ago and between the births of their first and second child her mother was cut out for about 18 months but her father never appeared to be. Now she's 'back in' again and sees hers and of course our GC; don't know about him. We noticed before we moved that his visits were becoming less frequent.
I remember during one conversation with our ES prior to the estrangement he told me "I wouldn't leave my bloody dog alone with them", seems he's quite happy to leave his children with their GM who now is a damn site more favourable in his eyes than we are.
