So I started talking to this cute girl on POF, opened her asking about favourite restaurants as she said her personality type was a foodie, and admitted I'd never been to her favourite to which she didn't reply.

I quite liked the look of this girl though so after a couple of days I sent her another message and made a joke of it, saying I'd have to remember to be more sensitive about her favourite restaurants in future, and she apologised for not replying sooner, blaming it on her friend distracting her. So we carried on chatting for a while after that, with the whole thing based around me guessing her unusual name, which gave me plenty of opportunity for playful banter which she seemed to be into. When I did eventually guess it I tried to number close by saying she'd be the only one in my contacts with that name, and she said she'd bear that in mind for future reference with a winky smiley.

When it was time to say goodnight she repeated my name back to me and said 'speak soon xxx' which all sounded good. She wasn't online at all over that weekend but when she did reappear on the Monday I asked how her weekend was, and she didn't reply. Two days later, she's been online loads but still nothing. Normally I'd just walk away, but as she has an unusual name I looked her up on fb and we'll be at the same wedding in 3 weeks where her best friend is the bride.

So I can't decide whether to make contact one last time, mention it to her friend or leave it and see her at the wedding. Opinions guys?

What if you text her something playful after a few days of radio silence.
Then when she replies, tell her you'll call her later. Or just call her later.
