I'm in pretty much the exact situation as you Cale so I'd be interested in any advice people have too. The lady I initially asked doesn't have time and there's a distinct lack of women where I am so I feel like all I can do is just keep going to meetings and hope someone appropriate to ask turns up.
Maybe if you speak to your initial sponsor that would make things smoother for you. I doubt she'd be offended. If you haven't got anywhere in 3 months maybe it's just not right. Or maybe she's waiting for you to initiate something?
