I'm struggling a bit with a very long term friendship. Known each other for ages but she has had marriage problems for over 20 years and during that time started divorce proceedings twice then stopped it. For all those years I've been a good friend and spent hours and hours on the phone listening to her and trying to be supportive. But as it's gone on so long, she's changed. She's always been quite feisty but now she's very confrontational with him- every few weeks or months they have a screaming row, started by her over what he has or hasn't done. she's also been violent towards him and hit him/ kicked him on one occasion until he ran out of the house. He's behaved in ways that are not good, but I somehow can't get my head around how she lives now. It would cause a rift between us if I said to her that I didn't want to hear about all of this any more but I do think she's changed. Any words of wisdom?
