He bought you a house and pays for it? So is he the owner? Is your name in
anything? If not then he bought a house where he lets you stay. Otherwise your name would be in it. He seems to be very well off.

He can’t introduce you to his parents? He is likely married but can afford buying extra house. I am surprised he bought a house if he rarely sees you.

The guy isn’t available. Either married or has a girlfriend. Talking every day doesn’t mean much
