What do i do?

So apparently you miss me? umm okay?
thats just kind of stupid because you were the one
to end it like you did and you were the one to telling
me that you cant have me. and that we were are only
suppose to be friends, and that before was a mistake.
so how can you go around telling my bestfriend that
you miss me and that you want me back when you chose
this ending for us.
you made me cry for days and whenever we talked i cried
whenever i heard a song we had together i cried.
and now that my tears are all dried up and i did what you said
and moved on, you come back with an i miss you.
what do i do with that?
