I think that would be a deal breaker for me. Just the thought of my partner intimate with another sickens me. You have alot of character to give this another try but I wouldn't trust her as far as I could see her and saying that means no trust. And without trust what do you have. I would be as devastated as you. I can't think of anything more hurtful. I wish you the best my friend, you really deserve a better deal.
