Oh Water.....more ((((((((((((HUGS)))))))))))))) to you!
I didn't know quite how to respond to your sitch, until I read KAW. So, so wise.

This is so TRUE. You will just have to let him be. Let him do the pursuing a bit more. Be kind and responsive....but not too nurturing. Don't initiate much right now....he knows your offer is on the table. He needs to take charge of himself more. He almost seems to like that you do for him.....you offer time together. Hmmmmmm, was it that way in the beginning of your R? Did he do more of the initiating of things together?
I don't have experience with the depression thing....tho I think my H has some too. Do you ever talk with a DB councelor by phone? Mine, Joanne....is extremely helpful. Just a thought.
Continue to find things that make YOU happy each day....and take it day to day. That's all you can do at this point.
Don't beat yourself up anymore, either. Give it to God. It's outta your hands.
