Proper understanding required

Well i got something that has been pressing me for the last couple of days.
On thusday night i bumped to this gal whom i have known for 2yrs.
We haven't seen each other this year after i changed my sim card.
After that we went home together and shared the same bed with clear instruction not try anything.
The babe has been spending at my place since then but leaving today.
Everything has been on me meals,airtime and many more.
Including wearing my t-shirts and using my towel.
I havent touched her at all.
The question is what is she up to?
Mark you this is not the first time,its the third.Same story.
I have been asking myself a lot questions on whether should i ask for goodies or not.
We have been sharing the same bed for those days.
Villagers enlighten a brother.
