Cant stand the fact

Missing you isnt the hardest part.... its knowing I once had u that really breaks my heart Some times your mind doesn't want u 2 be in love. but deep down u know you are.... I'm just a girl standing in front of a boy...asking him to love her I wish I had the guts to walk away and forget about what we had. But, I cant because I know you won't come after me, and I guess that's what hurts the most. Everything you do, got me crazy over you , I cant stand the fact that she has you
