Thanks everyone for your responses!! I thought maybe it was just me being sensitive
texas*princess, they are probably looking for Rho Chis b/c your greek system is new, and the women there don't really know how to be Rho Chis. Therefore, the other university, with an established Panhel, can hopefully fill in and teach the women this.
AlphaSigLana, I don't necessarily think it's wrong to tell your chapter if a girl in your group is interested or not interested. I mean, if there's a girl who is really into your house, giving her a little extra attention during parties is ok. What's wrong is actually talking shit about other sororities to the PNMs. I think it's really common practice for the Rho Chis to tell their chapters how they are doing and such.
RockChalk, if you're not a member of the sorority who lost their house, and you're not affiliated during recruitment, as a Rho Chi, you shouldn't say anything. If a PNM says they heard this or that, you say, I don't really know why they don't have a house, but that really isn't such a huge deal in finding a sorority. Encourage the women to look for what really matters in sorority life, and they'll join for the right reasons.
