what should i do

I'm coming on this site because I feel like other actives may give me good insight to my situation. I've already talked about this with friends but they give me very generic responses and I feel like I need more advice.

So basically last semester my now ex boyfriend cheated on me with a couple of other girls in my house as well as other girls in other sororities. I found out about the girls in my house and was appalled at not only the fact he did it but that girls who knew he was dating me would still sleep with him. I angrily texted them and gave them the whole spiel about how that's not okay and how upset I was. The ended up getting mad at me and all their friends in the house sided with them.

At this point it feels like I can't even walk through my own house without getting glares. I see the girls and all their friends all the time and it's so uncomfortable. It sucks because I used to love my sorority, I used to love going to events, I even used to really enjoy going to chapter but after all that happened I started to really hate it. No girls have confronted me in person but it's just so uncomfortable. My ex is also now dating one of my sisters he cheated on me with. I'm considering dropping, has anyone been in this kind of situation before or have any advice?
