Hi Nevanna, Been following your sitch and your future looks so bright!
It's great that you and your H are sharing the gym as personal time together. I just think you could be a little less regimented about it and not get your feelings hurt if his attention is elsewhere for a while.
It sounds to me in your recent interactions that you and your H are still extremely sensitive about any old R talk-- and getting overly upset about little things. Of course you are both scared, after going to the brink of S/D and coming back... What more can you do to build a new R instead of rebuilding the old one? How can you reassure (maybe more nonverbally than verbally) your H that you are in it for the long haul, so he doesn't get so upset and feel like leaving the house every time you say something he doesn't want to hear?
Building confidence in your R seems like a challenge for you right now. More Acting As If might do the trick...
I'm getting so much inspiration from your sitch! My partner and I arfe coming back from the brink, as well. We'll have many of your same challenges.
