Don't know if I belong here....

[Okabe]

This may seem like a dumb question.
In what I've read about detaching there is a lot about developing independence and not fostering dependency (unhealthy) in the person you are with.
In my relationship I have over the years taken on more and more of the housework, bills, outdoor maintenance etc.
Is it healthy for me to back off on some of that and let my W take care of more things? Like getting the oil changed in our van? Planning a few meals? Shipping x-mas presents to her family?
Or does it really make no difference? I feel like she sometimes takes advantage of the fact that I'll "just take care of it" (although I let her, so I can't blame her for that) and that perhaps I should be drawing firmer boundaries here.
