Hi ed Just found your thread.
Big hugs to you sweetheart. I know you are feeling down and emotionally battered by it all, but i do think you need to draw on all the strength you have and focus. You are being swayed all the time by his concessions, promises, ways out etc.
Think of it like stops on a tube train. The start is where you are at now and the end is where you want to be. Write down all the processes as the stops in between in order and do them one at a time. Head down, don't waiver.
Ie, CAB, Sol, House hunt, etc and do not listen to him or your mil and sil.
Do not even have a discussion with him. Pick some mantras.
'this is not up for negioation, '
'I do not wish to discuss this anymore'
'we have tried everything'
'i don't want to be with you anymore'
and keep using them over and over.
Treat him as if you are single- no washing, cooking etc for him.
He really needs to get the message that this is going to happen. He has swayed you so many times, he just thinks this is another one of those times.
pm me if you want to talk privately. x
