Should I get over it and move on or wait for her to figure things out?

I have been dating this woman for 7 months...we broke up for a week but got back together and have been dating for 2 months since then. We had a really great relationship before we broke up...but she began to distance herself from me and I broke up with her because there was little to no communication. I missed her a lot and realized that I loved her more than I had thought so I contacted her and we talked and decided to try it again. Since then we have slept together twice and I rarely see her although she texts me every day and says she loves me and misses me. I have told her that I want more out of the relationship and that I can't make it work by myself. She told me that she was convinced we would get married and be together forever but she closed her heart when we broke up and she doesn't know how to open it up again and she is scared to get hurt. I am done everything I can to show her I love her and want to be with her exclusively..forever. She always says she is confused and doesn't know what to do...says she is heartbroken at the thought of losing me but I find that I am putting a wall up now because I don't want to get hurt...it hurts to not see her and have physical contact...although when we do see eachother it is really good....good visits and passionate kisses and cuddling...although nothing else. I am alright with not having sex but I need to be fufilled emotionally and physically otherwise. I just don't know what to do anymore...I love her with all my heart and I don't want to lose her but I think maybe I need to end it...maybe that will bring her back...maybe she will want to be with me if I am not so available? I don't think it should be so hard for her to decide what she wants and if she doesn't want to be with me I could deal with that if I knew it for sure...I feel like I am getting mixed signals. Any advice would be greatly appreciated...thank you.
