Boyfriend wants to move out but stay together?

Anonymous
Some background, we are in are 30's together for 2 years. We've lived together for 8 months. We've been having little arguments here and there but last week it was a little worse than normal. I got angry with him for staying out until 5 in the morning when he went out with friends and not checking in with me at all like he usually does. I was worried something happened to him. I knew from the beginning he liked going out with friends to let lose and never had an issue with it until the last few months. He's been coming home later and later. Now he's accusing me of not trusting him and trying to 'control' him. So his solution is to move out so we have space but stay in a relationship. Also he says he doesn't feel completely comfortable in our living arrangement because I own the house and if anything were to happen with us he's the one who would have to move out and he doesn't like having that hang over his head.
I feel like this is going backwards in the relationship which I don't like and I also feel like he may be wanting to see other people even though he'll never admit it. Living apart will give him the freedom to do so and stay out as late as he wants. Opinions? Is this a reasonable request or is he trying to put me on the back burner while he sees what else is out there?

To be clear, no I do not text or call him throughout the night when he's out. And no I do not ask him to constantly check in with me throughout the night either.
He used to be different. He would call or text me when he was on his way home or to let me know he'd be out super late or spending the night at a friends. He also asked me to do the same when I was out. I'm suspicious because of his change in attitude about the whole thing.
