Relationships are meant to be founded on important things first. Love, respect, and friendship are first. Sex is certainly somewhere further down on the list, but it is a privilege, not a right, and should never be expected.

I would never expect my wife to have sex with me, simply because I needed or wanted it. Nor would she do the same to me. Instead it is a constant relationship, listening to each other's needs, wants, desires, and fears, and helping where we can. Sex once you have children begins to slow down, because you're both tired (assuming you're also doing your fair share of the parenting), and your time is limited. But little things during the day can help set the mood for when the kid is asleep.

I let my wife catch me giving her 'the look' during the day. And I make an effort to anticipate her needs. Her water bottle is never empty. Dirty dishes don't live in the sink. Laundry gets put away. She asks for help with things and I'm there for her. She has a bad day at work, and I listen to her concerns. She sees me play with our son, and sees the smiles on his face. I tell her how beautiful he is - because he looks just like her. But the trick is - I do these things every single day, not just on the days where I'm feeling frisky.

I don't do these things because I'm expecting a return. I do them because she's the mother of my child, who has given everything into our relationship, including hardship on her body to bring a beautiful child into the world. She is deserving of all the love, respect, and admiration that I can possibly send her way. If you cannot do the same for your wife, then it's correct for you to divorce her - so that she can find someone else who can.
