Nate married you because he saw cheap work hand at home while he is away at work, he works in military

He doesn't care about you, he has his own interests and his responsibility, he doesn't have time to think about you too, he doesn't even notice you at home when he returns

All he cares about is discipline, and when he returns home, he cares about warm cooked food, warm bed, clean bed and clothes, that's all, in the morning he goes back to base to train recruits

In the evening, he returns home, and you're cooking dinner
