<human>: Summarize the given text in a few sentences.

A couple of days ago, I got into a huge argument with a close friend of mine. We started arguing about how she was leading me on. Everytime we were together, she would link her arms with mine, hug me, physical contact, etc. I didn't mind it because I've been fancying her for a while. When I told her how I felt about her, she said that she does have feelings for me, but was scared that a relationship would ruin our friendship. 
This is when the jealous bitch inside of me takes over. I start questioning her, asking why she would initiate the physical contact if she knew that she didn't want anything more than what we have. The argument then escalated to  the topic of her ex. She still has feelings for him, but she hasn't talked to him in over a year. I asked her how she could still have feelings for someone that may not even be there anymore? How could you still waste time being unhappy that you are not with him if you said yourself you have no chance with him? She took this as me **telling** her to get over the ex to be with me. I stopped her right away and said this wasn't what I meant. She proceeded to say "it's you saying whatever you want and me misunderstanding". I apologized and she didn't accept it. I know that it was out of spite, so I decided to stop talking before I made it worse. We haven't talked since. 
What should I do? I don't know how I can recover after bringing up her ex.
<bot>: I developed feelings for a girl, she didn't want to commit to a relationship, I turned into a jealous wreck. What should I do?
