Personally, I wouldn't focus on not doing the typical things that you do for him. H can then think about how negative you are and that you are a mean person. He will see you as a punishing mother, when the idea is to see you ( and respond to you) as an attractive spouse. If he treats you in a childlike way or with disrepect, then call him on it. Refuse to do that particular activity at that time until he apologizes in some fashion. Don't let your anger at his lack of spousal emotional support come out as a general "protest." He won't get it.
I think you are too much in the "mother" role with him. You both need to carve out more time to relate to each other as spouses. I know you go out to music concerts and have gone for walks and such, but you need to make time on a consistent, regular basis. Let him learn to make plans for you...it can be as simple as pouring you a glass of wine and renting a movie. You need to spell out for him the things you need for him to feel like a "man" to you again( without mentioning he is not manly). You deserve to feel like a woman. I remember asking my H simple things ( ex. " I would love it if you opened the ( car)door for me..oh, that's so nice, smile, kiss). My H chose to walk away from this identity and I needed it back. Figure out the things that work for you; it really is the exciting part.
What I am trying to say is to draw from positivity and things that you want, but be stern about correcting bad behvior on his part. No need to go on strike.
