M180, it's good that you've come over here to ask these questions and that you're taking everything on board. I think your wife needs time and space. If you discuss your feelings with her and ask her about her feelings too, that will be good. I think right now is not a good time to pursue any sort of physical intimacy because she clearly said she's not ready for that -- I'm glad you apologized for the kiss.
If you are meant to be together, you will be together... in the future. Sometimes relationships don't work out... sometimes they do, people reconnect against all odds. Have faith that the future will bring what is necessary.
For now, you are in a good place because you are improving your health both mentally and physically. Keep stepping! Good work M180!
