busy fiancé

Alexis
I really need advice, my fiancé and I haven't been getting along. I'm a stay at home mom to a disabled son and he work long hours as in 5am-7pm. He's only off on Saturday's and sundays. And on those days he likes to relax or catch up on things. Problem is, he doesn't include me into those times. He complains that he doesn't have time to talk or he just wants his space to relax but he doesn't understand I never get to see him and would like to spend time with him since my only interaction is a child all day. My question is how do you ladies balance it? I'm just to the point where it feels like he doesn't want me around. And his job wears him out I get it but he doesn't want to do anything with me because he's so preoccupied with other things that it causes me to question him and if I should stay. He's an engineer so it's really hard on him plus he goes to school.
