Shelby, I am so very sorry you are going through this. Betrayed is how I would feel, too. Actually I did go through something similar. No one can tell you what you “should” do. Wise council will help.
God has given you a gift of discovery. IF He has revealed it to you, then He has a plan of getting you through it. I wish I were in real life with you, I would hug you. God has a plan, for your good. I promise this is true. I know it doesn’t take away the pain, but I pray it gives you strength, in Hope, that He is has good plans for you…to give you a future.
