Should I forgive or forget?

SHE,the one I once loved so much texted me yesterday.I should be happy for it because I missed her message.I didn't know why when I received her message, I get so angry about it.The way she tried to care for me.urghh!what's that for?If she care for me,why is she hurting me in the first place?She asked,'do we still remain as friends'?I should have replied yes.But then I said,'Do I still need a friend like you'?Very mean,right?Atcually I thought i could forgive her for what she did to me.But sighhh.I still couldn't.Everytime when I think about how she left and everything between us,I shed a tear=( I really want her to care for me but the more she cares,the more hope i'll put.She doesn't realized that I don't need her caring for me when she has gone with another girl.I didn't want to get hurt anymore.So I think the best way is to delete her from my life.NOT EVEN FRIEND!
