Last week my girlfriend was confused and I didn't know what she wants... then she told me that she is in and out of love ! I lookked back and told her why you didn't tell me from the first time... then she said I don't know my feelings changed . But she loved me sooo much and I know...

As hard as it is to do, just let her go and end communication. She might realize what she's done and how much of a mistake she made, and come back to you.
