Can you help me ?

Hello  Frans , 

I  wanted to write you because  I need your help . I've been having many problems with my girlfriend . I don't understand  what happens , we have had good and bad  moments,  but we have had  many problems lately . she always  tell me what happens to you , you no longer become interested in me , you no longer love me as before and all because of football . Also she said to me If you're not going to be interested in me , we break up . I don't what to do ? I love her a lot and I don't want to end it , but I don't want to stop playing football because it is my passion what do you think I should do ?   

Sincerely,

Fernando Jimenez
