Separated in the same home

[2inlimbo]

My husband and I are now re-separated in the same home. We were doing great til I backpedaled and my H flipped out and now is on the D track again. My question is, he wants "space". How do I give him space, living in the same home, while at the same time I am trying to salvage our M. Should I be cool when he comes home, or should I be warm? He wants space, so ow do I show him that I still want to make it work?? Any insights would be appreciated....
