Thank you so much Stillpraying and Justasking.
You are right. It could be a temporary bust up. Although she is not the sort of girl to hang on in there if he is not buying them a flat, getting a D, not spending money on her, seeing a lot of his children etc etc. And there have been many arguments between them recently, and he has got sick of being controlled. I feel it may have burnt out; it was just about sex and a 'fantasy life'.
She says that she got too much hostility from everyone ie MIL and FIL.
My H, however, told me last week that he 'wants peace' (ie what he found in me) and not 'excitement', which he wanted three months ago.
I feel terrible and exhausted. Will leave in God's hands, I no longer have the strength. Hugs.
