Big Sis/ Little Bro Jealousy :[

[loveADPI]

So I don't really have anyone to just talk this out with so I decided to come here. A few months ago I started dating a boy who is rushing a fraternity as a sophomore. I go to school two hours away and visit on weekends. He just got his bid and immediately a girl who he was friends with in high school (same age) tells him she is taking him as her "little". I know this is usually frowned upon by NPC but they obviously don't care. But anyways so I find out at least she is an ADPI right? Well I meet her and shes really fake and just obviously isn't happy with my presence. Ive tried to be nice and I mean I cant tell him he has to tell her no. I just need someone to tell me its gonna be okay :[ I just really am so jealous, she already told him all of her sisters LOVE him. I know im his diamond girl i'm just worried I wont be when they are all over him all semester.
