<human>: Can you succinctly summarize the text in 1-3 sentences?

I [27F] broke up with my [26F] ex a year ago. The break-up was kind of emotional, and I admit that I treated her like shit and did terrible things. For example, I kicked her out of my house after she flew 2,000 miles to see me. There was yelling and crying, but I think even though she was hurt and angry, she kind of understood where I was coming from (at least I hope she did). 

Anyways, the last conversation we had she seemed calm and resolved, and said that she would still like to remain friends. At the time I was not ready, there were still too many emotions, so I told her I needed some time. 

Now a year later, I am thinking about her a lot. I don't have any intention of starting a romantic relationship with her again, but I really do miss her friendship. I also want to apologize for my behavior, and let her know that I still do care about her and have not just forgotten about her. 

However, I'm afraid that if I contact her again, I will just be bringing up bad feelings and drama back into her life. For all I know, she has moved on, forgot about me, and wants nothing to do with me. But she could also be missing me too, and waiting for me to make the first move again. 

Is it worth it to risk bringing up painful memories to apologize and maybe try a friendship, or is she better off without?
<bot>: Bad breakup, she wanted to remain friends but I wasn't ready, a year later I am. Should I email her and possibly bring up hurt feelings, or leave it alone?
