They are both married for close to 7 years but no child yet. The wife got tired of waiting and packed out the house. After so much pleading from family and friends for her to return back she finally agreed but the shocking thing is that she's already pregnant and the husband is not the one responsible for the pregnancy. what will you advise the man to do?

You know the answer already ....

Begging and pleading won't help the situation especially now that she's pregnant for another man.

You see this marriage thing, child bearing or raising isn't compulsory. Our fcked up mentality is the reason we expect babies from newly weds after about 9 months.

If and when he falls in love again, he has to come out straight and explain his condition (Azospermia or low sperm count?) to the new woman. A lot of good women out there don't need any more babies, all they want is a father and a husband. BTW, both conditions can be resolved medically.

There are some basic facts we all need to tell ourselves and stop putting people through needless pressures. Everyone won't bear children, we all won't get married, everyone won't get wealth, some people will struggle and die poor, some will die untimely. These are basic life facts. However there is that one thing we all can achieve EQUALLY. It is called satisfaction/contentment.

Go after a woman that finds satisfaction in your status and live the rest of your life a satisfied and happy man.
