Hi All
Well dc's now know about the separation - it was as awful as I thought it would be and there were tears from all four of us but I think we handled it as well as we could and made it clear that none of it was their fault and that we would always be a family, just couldn't live together anymore.
Initially it was a relief, but must admit I'm struggling now (I guess part of the grieving process). Not helped by how easily dh seems to be moving on with his life. When he first talked about separation many weeks ago I knew there was someone else in the shadows for him. He was honest and told me he was friends with someone and he thought it may develop in the future.
So part of me is fuming that despite him saying he's been unhappy for many years and in his words he "gave up" with the marriage a year ago he could only end it when he knew he had someone else on the sidelines.
I'm not an idiot and to be honest don't really want to beat myself up about what may or may not have happened between them but it's obvious that something will and I guess that's something I've got to get my head around. As far as anyone else is concerned (kids, family) we've told them there is no one else involved which does smart a bit for me as even if nothing happened between them when we were still together it's obvious that this is a factor.
But I guess that's his problem and he has to tell kids/family in due course about her and they can draw their own conclusion.
Just desperately trying to keep positive - in hindsight perhaps it would have been better if this had all happened when we were working/at school as finding it hard having so much spare time for the next few days. Grateful that we've got a dog as she's been fantastic company for me and her poor little legs must be tired as she's getting plenty of walks 

Love and happy thoughts to all for the year to come xx
