So i met this girl at a club, we kissed.
I kinda know she wants me and is still interested, we talk a bit on facebook and i was just asking what she was doing in the weekends and she says 'studying', it's Examsperiod here in Belgium and she's studying law..
So she tells me she doesn't have any time to meet up untill after her exames, which is somewhere in February!

Now meanwhile I'm flirting with lots of other girls online and will go out some more the next days. I'll even be having a date the 17th of January with another girl. Now my inner conflict is, how to go about this?! Drop her and just find another one? Kinda ignore her and let her always start conversation? I really don't know..

Just give her the time until Feb and try again. Indeed, game other girls during this period.
You can just drop a "hi" every week or so and start a 5 minute conversation to keep her hooked.
