I could not stand being with my boyfriend every waking minute. And I've been dating him 3 years.
He needs to respect your passion, your hobby. Do NOT move in with him after two months. It sounds like he's a bit more controlling than anything.
You never should be happy or not. You feel the way you feel about something. It's something that can not be changed, trust your instincts.
Be yourself, and if he doesn't like that, kick him to the side of the road. There will be plenty other men out there that will respect your passion more, as well as who you are and how often you want to see him.
