Infidelity Support Group
Any relationship in which one partner engages willfully in sexual relations with another outside of the partnership is considered to have experienced infidelity. This breach of trust is often traumatizing for the faithful partner as well as the relationship, and support is often needed to heal emotionally and to decide whether or not the relationship should continue after...
Give yourself time to grieve this and start moving forward. You have a lot to look forward to, including someday finding someone who will not treat you like crap.
I'm sorry that you are in such emotional pain. You've been betrayed by the woman who claimed you were the love of her life, and by a friend who obviously who has romantic feelings for her. If you ask me, they deserve each other. As much as you are hurting, "The truth shall set you free". Now you know that she had been lying all along.
Hugs to you.
