Maybe you can find an appropriate time to talk with him and tell him you feel your relationship is too one-sided - i.e., you feel you're getting too much and he's not getting enough. You can ask him how he'd like you to contribute to achieving his goals and peace of mind. Hopefully, he won't ask for a divorce, lol. I would hope it would give him a little freedom to explore his own life without leaving you behind. If anything, it would show him you care about his needs too.

Me? I allow my husband to dress me up in waders and throw me into the river - he likes to go fishing.

I hope you'll be able to work this out.
