Not sure about GPA question either, but I second everything purplewindex said. My bf was apprehensive as well about the sorority thing and didn't know much about it either. Just reassure him that you will make time for him, and then follow through on that. Again, if your sisters don't respect your relationship, that's not the house for you. My sisters are so sweet. Especially when I clued them in about the situation, they made an extra effort to make him feel comfortable. That's what sisters do. Good luck during rush! I hope you find your home
