I don't like asking for things. Probably because I don't like saying no when I'm asked for something, so I find the act of asking for something as an imposition. Something like this is likely to cause for an awkward moment unless I already knew the answer was yes, so I would not do so unless we'd already talked about marraige, and he'd expressed some sort of interest but with reservations about my interest.
That's a lot of big words, but those are the ones that first come to mind. I forget the little words like "shelf" and remember the big ones like "receptacle".
