You are right. but the family and the now man don't feel preyed upon from what we have been told via media which has been pretty much NOTHING (although, I know- even though he was all machismo about it culture-wise it was "ok" yet our society says no it's not ok- then he dropped out of school etc. well, who are we to say he is miserable or not?) Keep in mind, in many cultures, the mothers raised thier grandchildren- I don't know if this was ok in his family or not- i'm not saying anything. just that I don't know. we don't know why he dropped out of school. He would have anyway for all we know.
What I am getting from Mary's lack of response is that she has recognized this as an inappropriate relationship. She may seek custudy of her children which will be tragic for them if she wants nothing to do with the father. That is what I worry about for the children. They have been seeing her which is good.
Bottom line is- as soon as he tried to kiss her, she should have left the scene and referred him to another teacher. Period. But she didn't. So now there are children to think about. And a father and a grandmother and a mother. I'll be interested to know how this turns out and hope the kids get the best deal.
