You are absoultely right! A kiss is not that much to ask for. She sounds like she has some serious issues. I can speak from experience, that I have 2 children, one is 4 1/2 and the other is 20 mos. Kids are demanding, especially 2 boys Anyway, yes as the primary caregiver (I see you help out a lot) my h works very long hours, so I am alone a lot... It gets rough. But I see you helping out and being there, and yes she works outside the home, but so do you. I don't see her point her. Yes everyone gets tired, god knows, and no, its not excuse for not getting a "touch" once in awhile.
I guess what Im saying is, although im not really offering any advice, I am validating you feelings, that you have every right to feel the way you do considering how she is treating you. I may not be up for sex as much as my h would like, but I am always affectionate with him when he's home.
I hope things change for you, if you love her you need to work on your approach maybe. If you just can't take it anymore, then you need to move on. You don't want to become so bitter that you can't get it together and jepardize a life you could have.

Happiness can be found, even in the darkest of times, if one only remembers to turn on the light.
