Have I pushed my ex girlfriend too far away?

I (30) broke up with my gf (23) in November after we were together for 2.5 years. She cheated on my 1.5 years into our relationship but I took her back. Our relationship was never the same because instead of her doing everything to show me she was sorry and that she loved me I was the one being asked to show her. I realized that if I was ever to trust her I needed to work on me and needed some time to myself. So I broke up with her.
In January she tried to get back together but I told her I needed more time. I had heard she hooked up with two guys after we broke up so I want sure if I was ready to take her back. Later in January we started to hang out and after a few times of hanging out I realized I was ready and wanted to be with her again. When I told her she freaked out and said that she just wanted to be single and that we were hanging out too much. I made a mistake and freaked out and sent her a bunch of long text messages saying that I missed her and loved her.
I made her cookies and a card on Valentine's day to show I still cared. She text me and said thank you but when I tried to see if she wanted to hang out she did she was busy.
I realized that she had started seeing another guy so I backed off and stopped texting her. After a week she text me just saying hi and started to text me once a week for 3 weeks. Last week she called me and asked to go on a walk. I said sure but during the walk all she talked about was her and her new friend Chris. How they have been going to bars, hikes, bowling and so on. I couldn't handle just being a friend when I still have feelings for her. The next day one of her friends told me that my ex only saw us as friends and had no feelings for me.
I was hurt so I text my ex and told her to leave me alone and give me space. I couldn't be her friend that I still had feelings for her. She didn't respond but she unfriended me on FB. It's been a week and I haven't heard from her. Have I pushed her too far away to get her back?
