First question the divorce counsoulr will ask is are you having sex? And you will say what for?
You must have a love life and enjoya and look forward to it. If you don't now, you never will. Stress of work and house building should not significantly change that.
Think about the direction "If you really love him, have sex on demand"...if the thought of that makes you sick. Run for the hills.
You see, for men the directions are "If you really love her, be romantic, help with her chores, bond, be emotional on demand" And if we do really love her, and feel that she will reward us with closensss and physical pleasure we will do that.
