Tell me exactly what I did wrong.

Sure enough, about 3:00 pm he called and said his mom was feeling fragile today and he might not make it out here. I didn't say "I've been waiting all day for turkey leftovers and don't have much to eat in my house," because he then commenced to complain about all the stuff he has to do. Go by his mom's house (her real house) and pick up some stuff, go to the grocery store, get back, make her dinner-- and by the way, "Are you [Lil] okay? Do you need anything?"

Sometimes... people wreck their marriage by putting their spouse at the bottom of their priority list, below others.

Other times.. that spouse sabotages the marriage, by putting THEMSELVES at the bottom of thelist.

if you were married to this person, then I would think that the best response to "are you ok? do you need anything?" would be, "well, I was actually looking forward to, and kind of expecting, that you were coming over with leftovers today."

That would have been the nice, no blame, yet communicative way to handle it.

Instead, you chose the "no communication, yet still allocate blame to him" route.
But then again... you're not even married to this guy to start with, so, not sure why you're posting in "the sex-starved marriage" forum about this

....

God, I hate being slapped with the demanding female label... I'm so low-maintenance, it's pathetic.

If you dont "demand", yet harbor all the resentment and entitlement of a "demanding female" without even saying what you want... in some ways, it's WORSE. At least with a demanding female, the guy knows what he's expected to do.
