Should I even answer her text message.... Yesterday was the day I def open my eyes and said "its enough!"?

Yesterday my girlfriend had a court day and I told her that I'd like to go with her. No one else from her family was going with her. She liked the idea about me going with her and I asked permission from work so I could be with her. We decided that we would see each other in court. I arrive on time and sit beside her. When I look at her she looks angry and upset. Let me tell you one thing. She is very moody, and almost every two weeks when end up fighting about any stupid stuff. She is very nice and good person, but her mood, and temperament is ugly. Well, I sit beside her and I reach for her hand just to let her know that I’m there for her and she takes her hand away from mine. That made feel very bad. I just sat there beside her. Her turn came up and the judge told her that she will need to attend to another court day since the case involved something more serious. When we got out she was obviously upset and started to cry. I told her that I could hold her thing so she could go to the ladies room so no one there could see her like this. She said that she didn’t want to go and that she wanted to go from there. She called her sister to see if she was around so she could pick her up and since she didn’t answer I told her that I could take her. That's how we had planned it. Okay, we get to the train and sat together and she is like pulling away like if she doesn’t want me to touch her. I asked if she feels uncomfortable and she says no, it just kind of tight. I’m like, hey that does really matter. I make conversation about the court, and she says she doesn’t want to talk about it, and talk about some other stuff and she barely responds. At time imp thinking, I’m here, that all that matters. As soon as we get to our stop I tell her that this is our stop, she gets out really quick from another farther door and starts walking away. I’m like, what wrong with her. I’m walking towards the exit and she is waiting for me and asks me for her book bag. As soon as I give it to her she walks towards the bus stop, she know my car is parked there, and she goes for the bus. I that time imp like. You know what, forget this. I walk towards my car, she goes to the bus and then she starts sending me texts. The texts said things like Know she knows I don’t love her, that she was crying and I didn’t even care, that I should forget about her, she calls me, I don’t answer, another text telling me that if I don’t talk to her and see her in the next half our everything is over, that it’s my decision, and then another text telling thank you for being there with her and for everything I did for her and wished me luck in everything. I’m like WHAT? I waited I thought about every that has happened before and now. I send her a text telling her thanks for everything and wished her well too and good bye. Just now she sends me a text wishing me good luck for a very important test that I have coming up. I’m like okay that nice, but what that does mean. Should I reply back? What should I say? Most def I don’t want to speak to her... What do you think about this?
