Have you said EXACTLY what you just typed to her? Because no, it's not too much to ask. Sometimes though I've noticed we all have a tendancy not to put things to our spouse as bluntly as they need to be....I'm as guilty as the next person on this.
I'm learning though to be very blunt...I am however getting very tired of having to constantly restate myself.
I did at one time though tell my H that just because he was there....just because he showed up for the appointment didn't mean he was holding up his end, I was still having to do everything....all he really provided at that time was a body. That (and I believe this is what you are experiencing) isn't the point of an "appointment".
I did have to blatantly tell him that just because he was there that wasn't enough...he wasn't participating. Climbing on top of someone who isn't interested and who doesn't participate does nothing for me. It leaves me feeling unwanted, unfulfilled, and unloved.....like someone kicked me in the chest. I'm sure my experience as a woman in this (whose H NEVER pursues) couldn't be much different than what you experience
So...out of curiosity, have you told her when she does this EXACTLY how it makes you feel?
