<human>: Condense the text into a few key points

My girlfriend and I have had a great run thus far, and I really enjoy being with her, but due to some not so great experiences in her past, she is rather suddenly unable to be around me without being very uncomfortable and needed to be away from me physically. She says that she would like to try anything to get back to feeling safe around me, but she didn't know what to do, and I'm just as clueless. I really want to help, but right now I'm worried that by talking to her I'm doing more harm than good. Any advice would be helpful.
<bot>: Lady and I have been happy together, but past issues make her feel unsafe around me, I fear trying to help it's making it worse.
