Aiyo auntie ah!
As saying goes, once your parents forever your parents, once
your mother, forever yr mother, once your papa forever your
papa.
Like it or not, divorcing is not their faults, but once they
loved you, they still will do, there nothing to address them as per
papa and mama as a form of respect of the highest honour.
If you current bf dun understand, it show he do not have a open
heart to except your once divorced issue. If he truly love you, he
will take it as respect you. Jealously is a man weakness
