I need help with my relationship

Me and my girlfriend of 7 months are having some problems lately. I love her more than I've ever loved anybody and she loves me the same but recently we have been getting in alot of fights. She gets very sensative abotu random pointless things and throws little pouting fits and tries to make me feel bad. Its been getting worse and worse lately. Tonight we had a big talk about it and she broke down and cried and said she doesnt know why she does it and she feels like she purposely sabotages our relationship. She says the more and more comfortable she gets with me the more she does it and she doesnt know why. She says she really wants help and wants to change but she doesnt know what to do. She says that she has never been in a good healthy relationship like this so its weird for her. She has a pretty bad family life so i understand where she is coming from. Im just really scared that things wont work out so I need some advice. Where should I go from here? Tweet
