Sooo..
Guy-main's father had an affair and child (unknown to him) in thailand.
Now, the Mother of guy-main finds out about this child who is now an adult and comes to the city to find his father..
Is there really any reason to be that upset, it's not like anyone's asking for money, yeaaaa, there's a mild segment of -infidelity-, but is that really an issue for long term couples..
Don't all trees have branches ?
The code of conducts have always been guidelines, rather than law.
Overall, the explosive reaction by the mother doesn't make sense.
You'd be angry at your husband for having cheated 20 yrs ago, but not THATTT angry..
