ok, glad you cleared that up for us. I was thinking that maybe you knew that they were going to use the pic and didn't try to stop it. Of course, you no doubt signed a release on the pic, but still there's some moral rights that you probably could have asserted.
Anyhow, it is what it is. Not like you intentionally got them to print the pic. And if your W wants to think that, nothing you can do about it. And if she figures it depicts her as a bad mom, that is HER thought... maybe a dose of reality...
Well, try not to spend too much time dwelling on it. It's just AN excuse for her to think you are the cause of her problems. If not this, it could have easily been something else.
Keep your pma up along with your chin and keep on keeping on...
