My girlfriend is unhappy and called me an emotional abuser

My girlfriend and I been together for about 7 month and soon 8. We've been happy for our time together and as a couple we go through arguements and we do resolved them together. We are in a long distance relationship but we are very loyal to each other but in a long distance relationship we all experience problems in our personal lives. I won't go into detail of how our arguement happen. But she told me she was unhappy with things going on in her life and a bit of our past arguments. I as a partner listen to her when she needs to talk, I try to give advice, comfort her and give her love and affection. But I am not perfect as I have issues myself as I had many bad relationships that never lasted and I still have a lot to learn about being in a detected relationship. I have made mistake but I don't want us to break up and I will hate anyone that give me that advice or options. I rather fix the situation as she would of surely broken up with me if I emotionally abused her on purpose but I wasn't aware of my actions or words. As I have a history of being abused as a child so I have trauma and my life hasn't been so effect by the abuse as I got through those dark times. But i don't know what to do when my partner says I'm emotionally abused her. I decided we should have some space until she clear her head while I try to improve and fix myself if I really was emotionally abusing her.
