Working day shift temporarily when you are used to nights would make anyone unhappy. Maybe he will have slightly less job satisfaction if he works a day shift. Maybe it will turn out to be fine. You compromised and moved into his place. He can compromise and adjust his schedule. Why should you do all the compromising?

If he starts describing what you owe him for switching schedules, remind him that you gave up your home and horses.

You seem to be hinting at a different question, but I hesitate to answer if you aren't asking directly. I get the sense that you are wondering about your general compatibility. He's 9 years older. He likes working nights. He's a homebody and a city/suburb boy. He wants kids and it's not clear you do.

He can be a great guy but not right for you. He can also look good on paper and not be right for you. I know that I had a history of dating really inappropriate people, so when I started dating people who were more stable, I sometimes felt like they were such a great catch - and they were, in a sense, but just not for me.
