To leave or not to leave?

Hello!! This is my first time posting here. I came to seek advice about a current living situation. Here's the scoop: on June 1st, I went from sharing a bedroom with a close, dear friend to a 3-bedroom duplex with my friend I'd just been living with and another friend of ours. After about three months of living together it became apparent to me that our new living partner-- lets call her Middy just for fun-- didn't really like me. We had been decent enough buddies before, but suddenly she became rude in our interactions. She would shoot me down in conversations around mutual friends, brush me off pretty roughly when I tried to invite her to come out on the town with me and my friends. Frankly, she was a pretty cold bitch all of the sudden, when she was not before. I knew something was wrong, but before I got the chance to visit with her in person I noticed she had eaten all my eggs (other roomie confirmed that it wasn't her.) Super little issue, I didn't think much of it and sent her a quick text asking if she'd pick up some eggs. When she responded with "if it's that big of an issue just put your name on them next time," I was a little hurt and angry, especially because I frequently went out of my way to pick things up at the store for her. So I proceeded to ask if she planned on paying me back for them. And she flipped out. I'll spare you the details, but it wasn't nice or pretty. Her response was along the lines of "Is that all you think about are the stupid ***** ***** eggs?" A friend of mine had passed away tragically two days prior, so I informed her that no, eggs were not the only thing on my mind. She did not seem to care. I suggested we talk about our negative feelings over a glass of wine and got no reply. So I confronted her in person the next time I saw her at home and said, "We need to have a conversation." I meant to ask her about everything and badly wanted to resolve the issue. She shook her head and slammed her bedroom door in my face. I lost my temper and texted her (probably stupidly), telling her that real friends talk things out. From here, she launched into one of the worst verbally abusive tirades I've been subjected to. She had a couple valid complaints about my living habits (dirty dishes left in the sink for a day, etc.) plus a whole lot of personal, hurtful jabs about how "self-absorbed" everyone thinks I am and how selfish, spoiled, fake, etc. that I am. Frankly, I was shocked to hear this. I am a performer and a musician and could see how she could get "self-absorbed" from that-- I frequently promote my music to friends and on social media-- but honestly, I care about my friends more than anything, including myself, and tended to her wounds just weeks prior when she had been mugged. I am a caring, empathetic, and loving person who takes my relationships very seriously, and she hurt me pretty bad. Anyway, I left to study abroad for the semester (it's awesome here!) and tried to connect with her on Facebook by asking very objectively what she wanted to do next-- did she want me to move out, etc. She blocked me. She won't communicate, at all. I'm frustrated and may move back to my hometown briefly to prepare my loving, long distance boyfriend for his move to the city I've been living in for the last two years (we've been together for three). However, I don't want to punish my other roommate for our fight and worry about the financial hardship on her if they can't fill my room in time. What do you think? Should I go home to a hostile, uncommunicative jerk or go to the hometown I left years ago for a few months?
