GM, have you thought about just telling her but no one else? I am in exactly the same position with teenagers, family, friends, job etc, but after years of holding back I finally did tell her recently. It was tough and is not over, but she is still my best friend in the world and I could not deceive her any longer. So far, though it is not settled yet, she is coming to understand and forgive. She still loves me and is growing to accept it. I don't know your situation, and I do not mean to preach or judge... I would never. Just asking with much empathy, honey. Sometimes, the love we fear losing is greater than we give it credit for...sometimes. Whatever, I understand and support your decision. Only you walk in your heels, baby.
Hugs
