Should I take this girl back?

Do you know the song "the past" by jed madela .. Listen to it and reflect on it .. I think if she is making up to you . dont ignore it .. Some girls can easily get tired when they felt they are not appreciated ..she is making an effort and i think that is the best proof that she is sincerely and deelpy in love with u .. Both of you should just move on from the past.. If u really love him fight for her and win her back .. And dont let the past back anymore
