So my friend Joseph was going to have a party on Sunday and that was all good and fine but his mom found out about it so it was moved to last night because they were coming back today. We were both going to go but at the last minute she backed out and said she didn't want to because we weren't going to have access to my car, although Joseph was going to take us home at about 1 a.m.. Her main problem was that she had to work at 11 the next day(today). 

So I still went and came back at 1. Throughout the night she was rage texting me and then she calmed down and told me she was scared at the house by herself and wished I was there, we live together by the way, to which I replied "I'l be home at 1." because it was 11:30 and not far from 1. She replies "Fuck you. You piece of shit." and I replied telling her why I couldn't come earlier, because Joseph was out getting someone and I couldn't find a ride besides him and had to wait for him to get back. 

I got home at 12:45ish kind of drunk and she completely ignored me when I went into her room and tried to talk to her. She was still awake and just told me to fuck off. 

Anyways, am I in the wrong? Should I have not gone without her? The main reason I went was because Joseph said he really wanted me there and I felt bad. 

What can I do to fix things with her? Also, my friends friend is having another party tonight and both my gf and I wanted to go, should I still try to go or is that too soon? 

Sorry for poor formatting and flow, I've got to be at work soon and just wanted some advice on what to do and how I should feel about this.
