Well...It took a little longer than I thought, but it's happened. Last night, my uncle sent a few Facebook PM's to my mother, accusing her of "poisoning your kids against me". Because, you know, at 27 and 30 we're incapable of thinking for ourselves.

His wife and I are okay, as far as I'm aware. To (belatedly) answer a question, yeah, she's technically my aunt, but she's only a couple years older than I am. We just call each other by our names.
I really don't understand him.

Saying he was "challenging" my brother's opinion, and "showing him what was logical", then turning his attack on my mother when we refuse to throw down and fight with him? Then dredging up things that happened before we were even born, and throwing out accusations about all of us not caring and showing no interest in his children? I don't get it. If that's logical, I'm a rabbit. Of course, it never occurred to him that we might have backed off because of his behavior. My mom's responses weren't exactly Ehell approved, so I'm sort of bracing for impact...There's more to come in the future, there always is.
This is why I can't be around them anymore. The few times I've tried the "beandip technique", I'm met with "Don't change the subject". If I wanted to play Chess, I'd break out my Chess board!

So, yeah. Pretty much a no-win situation, no matter what we do. Maybe it
is time to sever ties, because he expects everyone to agree with him and punishes those who don't. The trouble is, I can't do it without it coming back to my mother, and she doesn't want to cut ties with her brother. Not asking for advice on that, just sort of throwing my hands up in defeat. We haven't gone over there much this year, but there's a good reason for that. When we're over there, even though there haven't been any fights, we really haven't felt welcome. It felt like we were going through the motions for the sake of the kids, or something. I suppose I could continue to give updates as the situation unfolds, if anyone's interested, but it would probably just be more of the same. This right here isn't because we unfriended his wife; it's because we unfriended
him.
