Should I give up on my true love?

I was in a the most perfect fairy tale relationship for 2 1/2 years. My ex and I were head over heals and we were faithful and spoke about marriage... The last few weeks of my relationship I was going through personal problems and I needed to find myself. I broke up with my ex whenever I wanted her to realize how serious I was about a problem so...for attention(lasted a few hours longest was a few days). The relationship between us was perfect the entire time. I was her first love/relationship and the first person she had sex with. She was my first real love. We had amazing times together but we were help back by her family but I was very patient with her and when my own issues came It was just too much to go to her about. When I left her this time she didn't allow me back.. A week went by and she told me what she wanted was space and for me to figure out things.. at the end of week two an old flame wanted to start JUST a friendship.. I accepted because I was lonely but I kept my boundaries because I had my eye on the prize. My ex and I began to talk but she was cold she was angry I was friends with my old flame and said I lost my chance. I eventually realized my ex had someone who cared for her who was trying to be with her. I told my ex that I was so sorry for the hundreds of texts and calls and I realized that maybe she wanted to move on. She told me that there was someone else but they were just talking and they let them in because I had let my old flame in. We ended up talking about everything and my ex wanted me back so badly she was just afraid and this new person is also a factor...shes confused and I understand why and it was my fault but is it worth waiting.. She doesnt know what she wants to do..if she should go to the person she loves that scares her or go to the person thats new that doesnt even know if they want a relationship with her (they want someone else as well). I feel like I shouldnt be an option and I know that I have to let it run its course because me coming in the middle can cause her to always wonder what if about this person... its only been a month since we have been apart. So my ex is in love with me and her new flame is in love with someone else...it sounds like she entered a rebound relationship thats bound to fail but I shouldnt be an option....
