<human>: Can you give me a shortened version of the text?

My gf had been having some issues for about a week or two. She explained to me that everything we did/do would always, for some reason, make her think of me and my ex. Her and my ex never really knew each other except we all went to school at the same time. We talked about it and she said it was something she had to get over but it was making it hard for her to completely fall in love with me. I understand this and am willing to wait a long time for her. 

Then came the fateful question. She asked me if I ever thought about her while I was dating my ex. In my desire to be completely honest with her I told her that I did once, after my ex brought her up in conversation. 

I know that was a stupid thing to say and I immediately regretted it. 
She got up and left after that, leaving to stew in my own stupidity. I texted her and we talked a bit more, she said she feels like sloppy seconds and she doesn't know if she can be with someone that talked about her to an ex. (talking to the ex was over a year ago. almost 2)

She doesnt want to see me until tomorrow and I am scared that she will want to break up. I love this girl so much and I want to know how i can fix my mistakes. I don't want something that happened a year before we dated to be the reason we break up now. please help.. Ill clarify anything else, I can't quite think straight
<bot>: Girlfriend mad at me because of what I said a year before we dated. I don't want our relationship to end because of it. help
