last night I planned to ask a girl out, so I text her. The first message she replied instantly and even asked what is was doing (which mean she wants the conversation to carry on). how she still hasnt opened my message and its been like 12 hours.

In college she was the one to introduced herself to me, she is the one who always appraocehs me, she once left her friend behind to sit next to me. She even called me handsome once.

So i dont get why she would ignore me.

Should I wait a couple of days, and just ask her out?
