<human>: We've been dating for a year and a half and I stay at his place (a room he rents in his landlady's house) 1-2 nights/week, and it's not generally a problem since he's usually there first, though I've had to wait at the door a couple of times. I can deal with the occasional inconvenience, but a couple of weeks ago I stayed at his place the night before leaving for Asia for the summer and he had to go to to work before I left, and he told me not to forget anything because once I closed the door, I couldn't get back inside. Silly me forgot a whole bag of toiletries, including some I can't get over here that I sorely miss. Yeah, I know, that was dumb.

I've brought it up twice since he moved in eight months ago. The first time he mumbled something about not wanting to upset his landlady by asking (though there's nothing about extra keys in the contract, he brought me along when he signed it so his landlady could meet me), and the second time he sort of halfheartedly agreed, then didn't do it. His landlady knows me well at this point, and she seems to like me a lot. I even helped fix her cable once.

It's not about commitment (I think...). He asked to me move in with him after graduation a long time ago and he initiated the conversation about marriage/kids, and we're flying out to stay with his family for Christmas this year.

He'll be coming to my apartment more in the fall because it works out better logistically, and I offered to get him his own key. He seemed to think that was a weird suggestion, and worried whether my landlord (whom he also knows very well, my boyfriend and I were housemates last year in the place I'm currently living) would be okay with it. Huh??

Is it reasonable to want a key at this point for convenience's sake, or should I stop asking till he offers? I know he's under no obligation to give me a key, that's his prerogative.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Boyfriend of 1.5 years won't give me a key despite sleeping there 1-2 nights/week. Says he's committed, but doesn't want a key to my place, either.
