Let me tell you something... ya you messed up...But I can say this ...If you really love this girl...Do not let her go Do not give up. Only give up if she says I dont love you anymore...I'm not attracted to you anymore..Bla Bla Bla... I was in a similar situation minus the STD and 4 months went by with me giving them SPACE. They started to date someone else and everything but I never gave up.We are still together Now and I learned my lesson and everything is Peachy ... as long as they still love you there is a chance. Little notes in the mail ...Messages Dont stalk HER just keep yourself fresh in her mind...If it was meant to be she will come around..if its not then At least you can say you tried..
