Can I fall in love with him again?

Hubby was diagnosed a year or so ago and pursuing medication but it's not going well.  I haven't seen any improvement in him at all since we have learned of his disorder and began seeking treatment and counseling.  He is seeing a therapist and so am I.  We have been together 22 years.  About 10 years ago, I told him that whatever the hell was wrong with him was slowly but surely erooding my love and respect for him.  I feel that's where I am at.  I feel no romantic love for him at all.  I have no respect for him at all.  His shortcomings in taking care of things as well as his social anxiety among other things have destroyed our relationship.  He is a great guy.  He deserves to be with someone who loves him.  I do love him and want the best for him, but I am so very sad and devasted that my feelings for him have changed.  My dream is to fall in love with him again.  Is that possible?  Anyone else experience something like this?  Part of the problem is I feel I have developed as a person over these years...pursued friendships, interests and activities to enjoy life.  He works, watches TV and plays video games.  He has no friends, no hobbies.  People ask him to do activities and he turns them down.  Now they don't ask.  I am tired of suggesting hobbies or activities for him and he blows me off.  I would like a partner who is fun and interested in the world to go through life with.  Maybe it's not fair to expect him to be someone he isn't.  And we used to be the fairy tale romance everyone envied. it possible to fall in love again?
