I went to a friend's house about three weeks ago and got chatting to a girl for like ten minutes. She remembered me from fb, as we'd added each-other during freshers week at uni, and when we were talking she asked about stuff I post on my profile. She was quite nice but had also been drinking so I didn't think too much about her talking to me.
She seems sweet, and I'd like to get to know her better, but I don't really feel confident just sending her a message on fb. We have some of the same friends so I was thinking of maybe asking one of them to bring her along for a party or something? I feel awkward asking because knowing my friends they'd think I was really into her, but I just want to see if she's someone I'd consider dating. If she was, I would just ask her out simple as, but at the moment I just want to get to know her better.
Is asking my friend a good idea? Anything else I could try?
