My ex said See you soon and take care?

Hello I am just a desperate man that is looking for a real answer, … Well my ex-girlfriend breakup with me three weeks ago, I miss her a lot and I want her back, the reason why she left me is because she said that she was feeling confused and didn’t know what to do, but I know that she still have some feelings for her ex- and her ex have a girlfriend and he told her that he think that he love his girlfriend but he doesn’t understand why he keep missing her and thinking about her, I listened to the conversation when she didn’t even know that I was listening, but any ways since that day she started to change and act different and she told me that she need space, with I agree with her, and is being three weeks already, she called me last Monday just asking how I was doing, and that she have been really busy in school, she is on Medical School, which I know it’s take a lot of time to be in it… But she told me that she was going to call me latter when she gets a break and maybe have dinner or lunch, I don’t know what to do… I’m a scared that she can find some one else, and forget about me, I want her back, but I don’t know what to do… I really love her and when she left me she e-mail me this “baby I know you are going to great this semester. I miss you too and yes I am very busy with school all the time. we can have lunch or dinner sometime soon maybe this weekend?

and belive me I know that you love me very much and you make me feel very good. no matter what happens you deserve to be happy and to have love and all that stuff. I know you will find good things, whether or not they are with me. I dont know what will happen baby. we can just be patient. thank you so much baby for understanding me and being here for me. I really appreciate all of your love and I know that you are good and true. god will take care of us both ok. see you soon and take care :).”… So I don’t really know what’s she thinking, does she think about me? or she is just trying to live me little by little, I need her… I did give her a space, I don’t ask her back because I don’t want to push her a way, Do you think I still have an opportunity… I love her… please give me an advise.=:O(
