Help PNM problem

[bwaystar]

We have this PNM that's been coming to our interest meetings on and off
she told us the reason why she's been missing meetings are because she needs extra time studying and she also babysits. I have no problem with PNM who cant come interest meetings because they have work but i found out that this girl is also an interest for another sorority on campus. She always ask me if there is a lot of of work involve because she needs to study (we're going through colonization process)
but the next second she always ask me about frat socials.
I feel that she wants to join A sorority not my sororiy and my sorority is basically split in half

please help!!!

Thanks
