Thanks for the response and good advice. I was beginning to lose hope a bit.
I acted before I read your post and am not sure how it's panned out. I couldn't sleep very well the night before, kept waking up with panic attacks - that's my sleep now. Panic attack, heart pounding and look over to my sleeping son and it gets worse. So it popped into my head at around 3am to speak to WH and ask him if he would consider spending time with me. Not to come back to the marriage but just spend time with me, to get to know me again. I know - eek!
I decided to do it because I realised the LRT was too much like the version of me he fell out of love with - distant, remote, uninterested. So I've gone back to the 180 and am trying to be loving, gentle and kind. When I spoke to him this morning he was v standoffish and really annoyed, no eye contact, a lot of sighing, said a few times he didn't want to be in the marriage with me anymore. Which hurt but I figured, what did I have to lose? He was getting really annoyed with me so I left to go out while he had our son. I came back at dinner time and he was still standoffish, but said before he left that he would think about what I said.
