Her assertiveness is borderline annoying. Possessive chicks are often the most assertive.
If you want to meet her, I suggest doing this:
Call her now say "Hey can't talk long. Want you on a one-on-date this FRI evening. Join me for a drink at 8 at (place)?" Don't rush the conversation. But get to the point. 5-minute convo MAX. If she keeps the conversation aglow, let it go for 15 mins. but ALWAYS be the one who ends the conversation.
If she doesn't answer the phone don't leave a voicemail but text this after calling: "Just tried calling you
" Then go out have fun work hard meet lots of other girls.
