Should I tell my son that my husband is not his real dad?

AGONY

KAMPALA - By the time I met my husband, I had a baby who was one year old. We got married and had three other children together.

We never really brought up the topic that my husband was not the father of my first child. And I do not have any contact with the real father.

However, my husband's relatives have always known the truth, but they have never made a big deal out of it.

But now that we are elderly and our children have started begetting children of their own, should we tell my son that my husband is not his real father.

If he or one of his children dies, where will we bury him since he does not know any other home other than ours?
