I met this girl on campus a few weeks ago. She told me to add her on facebook, so I did. We haven't had any communication until I sent her a chat tonight. She was talking about how she was still not over her ex from a year and 4 months and how much of a bi*ch he was. As she was getting off she said "well text me sometime and we'll have to get to know each other"..and she left her number. I know she's not over her ex, so I'm not sure how to approach this situation though. I don't want to just throw it away b/c she isn't over him yet. She will be eventually. Should I wait a few days until I text her?
