Probably because he doesn't want you at his house.

I'm not sure it could be any more simple than that. Unless...

Unless he's renovating the house and has termites or a rat infestation that only he and the dogs can manage, but they have to go in there every night and day to ward off the evil vermin that live within his walls.

Which is likely not even remotely true, so I return to: he doesnt want you at his house.

After two months, even the most conservative of chaps will ask you to stop by and see his dogs just to see where he lives, etc. The least conservative would have been trying to have "movie nights" well into the third week - at his home.

Hmm, maybe he's lying and he lives with his mother, which is why he -again- doesn't want you at his house, because he's been lying to you. Or heaven forbid he lives with his wife.

Or perhaps he's homeless and his "dogs" are his two homeless homeboys he also lives with under a bridge in Yourtown, USA. While this last one seems highly unlikely, it still all comes back to...

Class?

HE DOESN'T WANT YOU THERE.

Wherever it may be, he's not ready to have you there for whatever reason. If it bothers you that much, perhaps you should bring it up to him. His response should tell you everything you need to know.

But do not, I repeat, DO NOT just show up at his house using the address you got from that Google search you did on his life, tax records, and public lien information culled from the local paper. If he wants you there, he'll invite you. If not, he won't.
