Hi, so I met this girl at the bar and we hit it off. I told her to come back with me and she said she couldn't cuz she worked at 6am the next day (dunno if that was a lie). She also had alot of guy friends she was with.

She snap-chatted me and I don't really understand how it works and apparently it was also sent to all her friends. I sent her a snap chat that was a personal message with a question (I thought the snapchat was only sent for me). She didn't respond.

When a girl doesn't respond I feel like value drops. How do I get back value. I was thinking about just ignoring it and texting her asking what she was doing tonight to try and meet her up again.

Correct strategy.

Don't follow up. Don't try to get value back on a silly text message.

Like it never even happened, brother.

Give it a few days and text her something unrelated... Or better yet, call.

Always assume the positive. If a girl doesn't respond there is usually a good explanation - something that kept her from answering. And as CharlesFinley said, don't stick with old messages. Just move on.
