(((kay)))) I'm sorry you are still going through these emotions so! Since you have been with the same guy for 2 years and you are "young" you really don't know how it could be without him now, or with someone else.. you might not have these same strong bad feelings about yourself .. or him... but you stay in the relationship because you are afraid of being alone.. or afraid of the unknown (aren't most people!)

Please come back and post more, tell us if you are in therapy for these feelings and all you are going through.... TC
