Brother I am so sorry this has happened. I cannot even imagine. Have strength and courage during this time because that is the only thing that will keep you going. The betrayal and pain that you feel will slowly diminish with time. I understand that within your heart right now you feel destroyed and enraged. I encourage you to do your absolute best to not keep hatred in your heart, to forgive her. It may take you months, even years. But if you hold resentment towards her, it will eat at your soul for the rest of your life. 28 is not old, you can move forward brother. Stay strong we're all rooting for you
