Thanks banana....the truth is I told DH to leave, something happened one morning, and I just snapped, can't remember what it was but it wasn't about the kids. He asked what he should do about contact and I told him we had split so it was no longer my problem. He asked to go for lunch and I put it all on the table, the lack of support, the going back on boundaries, pulling me up in front of the kids and the constant putting dsd above everyone else and she can never be wrong. I think he though he could sweet talk me into agreeing with how he wanted things to change, I told him its that or I walk right out there and then and that id gotten to a point of not giving a flying fuck lol.
The following 3 contacts have been much easier, but I think that is partly due to the holidays and DH being more chilled (and me drinking lots of wine and not giving a shit about the place). We will see how it goes, he knows he needs to step up, (he said if we split it would be terrible for everyone, even his ex as she's just moved in with her feller and needs kid free time more than ever).
He's got a long way to go from being a selfish arrogant arsehole but I can see he's trying. I've had councilling and we are going to go to relate.
I really do get on with my dsc, thay are really great kids, it's thier parents that are causing the problems with the guilt from both of them. Neither parent can seem to say no. Even sil sees that
