breaking up with a off again on again

its bad, really bad to meet the guy who breaks up with you then comes back, then breaks up with you and keeps coming back. Its a battle. They will SWEAR up and down that ur the one and that it will never happen agian. DONT GO BACK!!!!!!!!!!!!!!!!!!!!!!!!!!! EVER. Once is enough, if he loved you as much as he swears then he wouldnt have left you once!!!!!!!!!!!!!
