Not another one!!!
I can't help but think about her psychological state. Just because she's attractive doesn't mean she BELIEVES she's attractive. She's in a failing marriage and then gets around a child who fawns over her. I can understand how her mind could take that attention to the extreme...in part to uplift her own self-esteem...in part to punish her husband. I mean, who wants to lose his lady to a 13 year old?
Sorry, I was so busy trying to analyze her (with no experience! LOL!) that I neglected to say that these activities are sad and destructive to all involved.
