Sils have had a falling out and the whole family is involved. I'm kind of half involved on the side of sil1 who is getting married. I didn't involve myself but was brought into it. Sil2 has thrown a strop and won't talk to anyone now. Mil is very obviously laying part blame at my door and is barely speaking to me. Wibu to go talk to her and put my side across or just leave her to deal with the bigger issue of leaving her to deal with the fact her daughters aren't talking over Christmas and deal with it then?
