Most Helpful Girl
I'm glad to see most everyone sides with you in that what you are feeling is completely normal. Betrayal is brutal. Sometimes it is a wound that never heals. I agree that for How Ever Long It Takes - you should not be around them until you no longer feel such pain from them.
Its unbelievable the amount of selfishness in people these days. I'm sorry this happened to you, your best bet is to remove yourself from the situation.
Also - be sure to find an outlet (gym,hobby) to help you deal because that kinda sh*t can eat at you and you don't want to sink to their level of mentality.
