Hey man, I think Supremo pretty much summed it up. Do not acknowlwdge your last text and if sje brings it up (assuming she responds) then don't apologize or explain yourself. If you want to reopen use any inside joke between you. Make it short and sweet. Search the text forums there is some great stuff there.
