I do not understand who this "guy" is. Please clarify.
he doesn't know what to say
He won't go out with you again..
handy means "handjob"
It means he wants to get in there whenever he wants, potentially at times you wont be there to let him in.I don't know your situation, so you have to decide whether that's something you want.
He is probably shy
It means he is being polite.
Maybe hes embarrased that he likes you.
If the 'other guy' isn't doing him and the character returns then obviously a 'new guy' will be playing the part.
No. If he entered your apartment legally, he may exit. Otherwise, you will have a maintenance guy living with you.
The Apartment
he's mean and stuck up!
