She says she needs to find who she is?

She really does love you then because she is telling you what she needs and believe me if she wanted to find out who she is and deal with such things while she was still with you,it would get you really really hurt.she did the best thing.and you did the best thing too.she just needs time.maybe after she is done dealing wit her stuff she comes to you.
GOOD LUCK

If she tells you that she loves you then believe her. Right now she's confused about what she wants. She knows that she has feelings for you and doesn't want to hurt you. She just needs some time alone to "find out who she is" she wants to know what she's going to do with her life and you're a big part of it. She's wondering if she can see you two together in the future. I know this because I've been through it. Next to this... her feelings toward you could have changed and she doesn't feel the same way anymore but she cares enough about you to put it like this so she doesn't hurt you. Don't take it offensively if this is the problem just respect her feelings even though it may be hard. Give her sometime alone. Tell her you will give her time and if she needs you then you will be there for her. :) It will be okay everything takes time and a little bit of understanding. She will come around

It sounds like she has a lot to think about. At your ages, relationships aren't as important as other events like school and church. Give her time and space to figure things out without having to worry about maintaining a relationship.
