I'm sorry I have not been on here for a while and did not realise I had responses.
His complaints were that I put everything else above him in my priorities. I agree with him in relation to the time I spent with my poorly dad, and to some extent work, which is probably enough. He also said I would always nit pick with things he did, again I can see I would do this. Some things he has said I did simply aren't true. It's luke he is trying to re-write history to fit in with his decision to leave.
He was fine with me moving back in, he slept in the same bed and would cuddle me nearly every night. He would bring me coffee every morning in bed, but he still continued to see her and eventually left. I tried to do the 180 thing and never tried contacting him. I would try to act indifferent when he was at the house with me, but he still left. He said living with me was heart breaking.
I continued to do the no - contact since he left, he has been in touch many times and has even said he misses me and admits he still lives me. But it's just words, he is still seeing his mistress and I suspect he is in no rush to leave her.
