I didn't get a chance to write on my thread yet but I made some realizations in the past few days. It sounds like you're doing the right thing. On the other hand, I believe your husband loves you. I believe he's struggling but you can't give up on him. He's still there with you. It's not too late. Maybe he does need some space but I'd say just to do loving things for him sparingly, flatter him with compliments, flash him some beautiful smiles, and give him some space. He still loves you. I'd do anything to be in your position because your marriage can be saved and happy again. Just tell him how great he is and give him a foot massage without asking anything more. Give it some time. You two will be together!
