So, you vibe well, get into a good make-out shesh but for whatever reason don't f-close but get her number. General consensus is to not get her number because she will give it to everyone, but do you still try to ask her for an ice cream/coffee or whatever?

Had a really nice girl myself but it was getting too late for me (appointment next day) and she said she wanted to go to her friends (probably good indication that she didn't like the making out) and gave me her number. Next day she rejected me when I proposed ice cream, I just ignored that.
