My advice

Dear X,


You certainly have a big problem! Firstly, I think that you should know that she can have different feelings and may be, she doesn't love you,
I also think that you should talk to her about your feelings.
Finally If she doesn't feel the same, don't worry! There are more girls in the world and you can find one better!


I hope that my advice  helps you!
All the best
Agony Josep
