The weekend before last, we all had a major fallout. The EOW was going pear shaped as always and I won't bore you with the details but there was a catalyst on the Sunday and I went up to our bedroom to get away from it all. SO came up and I said I had had enough and I wanted him to move out. Despite all our talks, nothing had changed and nothing would change and I was sick of talking to a brick wall. He then went downstairs and had a massive row with SS18 and his girlfriend and booted them out of the house. He was doing dinner and they were back in the house when I went down for dinner. I went back upstairs, heard another row going on, then SD16 shouted that she was going home as she had an exam the next day and couldn't revise in that atmosphere and that she had had enough of the "silent treatment" (shouted upstairs for my benefit). I wasn't doing the silent treatment btw, I was upset and angry and couldn't be arsed to talk to anyone. I wanted to speak to SO without the kids around - fat chance. Anyhoo, next thing SO comes up and says well you've got what you wanted, everyone has left. We talked some more (and argued) and I still said I wanted him to move out. He slept in the kids room that night, and we were both upset and exhausted the next day so we agreed not to talk that night. Tuesday I said I had been thinking and how about the kids just come over a couple of times a week for dinner and/or he takes them out rather than staying (they only live 1 mile away). He said he wouldn't do that. Over the next couple of days we compromised and agreed on Fri and Sat every other week (currently Fri/Sat/Sun nights EOW and a night in the week - 4 of us in a 2 bed house - and a dog). I said things had to change otherwise we would split up for sure (4 days of discussion in a nutshell!). SO has spoken to his kids and they were OK with him but not great - they haven't been over since the big row. SO met with them last night to talk things through (away from the house) and he came back and said they had decided they didn't want to come over at all again. Not to visit or stay. They will meet up with him still, but they don't want to see me. Even he said "I think they are being immature as they are also to blame for the situation" so I'm pleased he backed me up. So now I am the evil SM, when it is SO who has let it come to this. He thinks they will come round but I'm not so sure. I actually don't care that they don't stay, but am pissed off that they seem to think it's all my fault! We actually got on when we all chatted, and I feel bad for SO they're not staying over, and it will be very awkward now if we do meet up together. Can't believe we've gone from nearly splitting up to the kids not staying at all in 10 days. I'm happy for me, but feel sorry for SO even though he says he's OK about it. I feel at last like he is on my side though and backing me up - maybe the realisation that he was really going to lose me actually sunk in, not just idle threats. Sorry for long post, just unloading I guess.
