I'll attempt to be helpful for once :P.

Okay, does your chapter support the shit out of sorority's philanthropy events? Like do you show up with 50%+ of your active members and actively participate in the things they do? (Like their pageants-if they do that kind of thing on your campus, banquets, fundraising events, etc.)

If not, then that's where you start. First, you have to develop good relations with them- which your chapter doesn't have.

So what you do is you actively support EVERY sorority (even the not-so-good-ones) in the activities they hold. And what I mean by "actively" is don't just show up..if it's something that allows for participation and competition, have brothers partake in it. Make your pledges go too.

Once you show that you actually care and you support them, they're more likely to do events with you. I suggest that before you ask them to do socials, perhaps team up with a sorority for a philanthropy event. They'll be more likely to do that. Maybe it'll be out of pity or guilt at first (like a "return the favor" kind of thing), but eventually you'll develop better PR and your problem will diminish.

There's also the other things you can do like chapter meeting visitations, serenades, etc. but that's more basic and superficial.

Hope that helps.
