I don't think it's about choosing a side but it is important to call out the horrible behaviour when you see it, otherwise you could be seen as enabling the mistreatment of the one being targeted. It's important to hear both sides and just see both parties as fully functioning grown adults instead of making excuses based on age/past negative life experiences etc. I certainly wouldn't just sit back and say nothing as then you are allowing mistreatment continue, and that's basically choosing a side anyway. The issue is the initial cause of the conflict and that's what needs to be addressed ... so many families prefer to rug sweep and pretend an issue hasn't happened which causes resentment and (I believe) is a major reason why estrangement levels are so high at the moment.
Well, our problem with DHs ACs wasn’t historical grievances etc.
They wanted money, monthly, to prop up a combination of reckless debt, alcohol addiction, and gambling addiction.
We said ‘no’. And then bouncing estrangement started -for 18 years. 🙄
Then we got into the ‘all old people are a burden’ routine. We never once asked them to do a thing.
Luckily, my family are the complete opposite, so we didn’t miss his lot too much.
When he died, they waited expectantly for the inheritance they assumed they’d get.
However, he’d changed his Will. They got nothing.
So, as I say, I hope their unkindness keeps them warm in the Winter. 😉
