I have been suspecting PA, but she would never own up to that. She won't even agree that she has had EA. Crazy thing is, this kid is not even her type. Yes kid, he was 8 years old when we first met. So he is a boy to me period. I feel like he thinks he can do whatever he wants at this point.
Normalcy and common sense go out the door when EA/PAs happen. So don't even begin to try to figure it out, because you won't. He might be a boy to you but not to her. Why would she admit to something that would cause trouble? My bet is that they will go even deeper down that rabbit hole.
There are moments in this life when you are so confident in the rightness of your actions, that not even for a second do you consider the option that you might be wrong.
