Setting of boundaries is in order here. Let him know that you do enjoy hanging out with him but you need alone time. From here out, he can only come over [insert situations in which you would like to have him over] and enforce your policy. Call him out every time he oversteps the line. If he takes offense, that's his problem. Dropping hints won't help this and you shouldn't have to hide in your own home. I didn't do this enough with friends before and my priorities got all messed up. Never again.
