That is definitely a possibility, and I'm sorry for it. I don't think you have any control over what she says, anyway--she could be, right now, telling people that you have trouble in your marriage because you look at porn. I hope that she is or will be mature enough to realize that nothing is ever that simple, at least in the long run. I hope that everything works out well for you.
