Hi BI, I am so sorry that you are getting nothing from your H. I know how bad that sucks, how bad you just want to be held and told everything will be allright. I am doing that for you, even if it isn't physical touch, I feel your pain.
I'm going to share something that happened to me a couple of nights ago. H and I basically are getting along very well except for intimacy, which is in part due to lack of time and privacy from the kids. Sunday night he went up to bed and I kissed him goodnight and told him that I wished we had some alone time since we hadn't ML since October. He got a little cranky and said "instead of lecturing me and talking about it why don't you DO something." Well, it kind of pissed me off since in my mind I thought I was doing something. Unfortunately S5 had already crawled into our bed for the 2nd time so doing something at that minute didn't work out.
I know over Christmas you tried to get close to your H and he rejected you. Can you try again? Maybe reach out and touch his hand. If I were you, I wouldn't bring up the seperation. It is not what you want, is it?
