IMO, women are overwhelmed with jobs, kids, homework, housework, dinner, etc. They need kindness, understanding, and help. I don't know your circumstances, but dating regularly while married can help to bring romance back to a woman.
If you ask me, women use that housework kids dinner I'm so tired excuse for not wanting intimacy far too often. I work, I get then kids ready for bed, I wake the kids up and get them ready for school, I do laundry, I do dishes, etc. and on top of that, I fix the cars, mow the land, do house repairs, and other traditional 'man' jobs without assuming that the wife should chip in, yet I still have energy to devote to the relationship.
