I don't know if this is relevant but I am including it in case that it is. I have been taking care of all of our needs since day 1 of our relationship. I do not have any regrets about this and it has never seemed like a bad thing to me.

w does not drive by choice, I do all the driving
w only worked a regular job briefly when I met her
w is an accomplished artist but the earnings on her best year were about $4000. currently she is earning almost nothing
w takes good care of our kids (I consider this a full time job and I am glad that she does it)
I cook all our dinners and usually clean up after
I do most of the cleaning
I spend time with kids every day
I pretty much don't do anything separate for myself except for 2 times a week judo workout but even this I do together with oldest son.

This situation has never bothered me until we stopped having sex all the time. Now I think about it.

Do I do too much? Is it possible to do to much?

If I pull back, is it right to use all of this leverage I have? Won't that just push her further away.

I have no idea where to go from here.
