What to do :(

Okay so almost 3 weeks ago my relationship ended. We were friends for about a year and a half and I've always had a thing for her. The guy she was dating was a douche and he left her... twice. After the 2nd time she was heart broken again. And I was there for her. I eventually told her how I felt about her after a few weeks and a few months later we started dating. Everything was amazing. Nothing felt weird. Everything felt right. We fell in love fast. Then after spring break she wanted to talk and told me that she needed time to get things in her life in order. I tried my hardest to keep the relationship going. But I couldn't. I've tried a few times to try and salvage something. But I was unsuccsssdul. Yesterday I spoke to her and I later everythinf out flat on the table. I tried one last time to try and see if things could work. But again it wasn't working. She got frustrated with me and started crying and felt like I was trying to force it on her. She told me she needs time to grow up and get her life together. And I got upset and asked her why she told me all these things in the beginning and when broke those promises. And she told me that she knows I love her and I know she loves me. She said she really wants to be friends but it seems hard because we always seem to talk about the same thing. But I told her I didn't want to lose her and that I wouldn't bring it up anymore. She said she needs time and I really want things to work out. What do I do? What can I do? HELP PLEASE
