This is an issue of national concern. I think one of the ways to solve this problem is by jamb herself relieving the weighted point placed on waec grades. Even some few schools who claim not to engage in malpractice actually do underground upgrade of score.

I once marked waec papers and I feel the pain. How rotten our education system has become!

Enough has been said. And I must commend the commentators for their sensible responses. However note this little contribution of mine.
1. You are not wrong to have requested that you own the land to yourself. Though the husband might feel bad most especially if at the time he made the proposition he's not financially capable.
2. But then, it is not really advised that couples dig deep into their partners affairs. Digging deep will result to unfathomable discoveries. Just in your own case. Imagine you didn't search his phone, we won't be here for this discourse.
3. If our parents pack out at every little issues I doubt if anyone will grow up seeing his/her parents together. Rather than packing out, you could have deviced a means to get *5 of your money back from him.
4. And to now say that you discovered you are pregnant few days later. Nd most amazing part is your husband still didn't deny or accuse you of infidelity, it shows beyond this flaw of his, he's a responsible and mature guy. Even you have confessed you don't want your children to grow up without fatherly love. And to think another man will take care of your children like his own is very wrong.
5. I think both yourself and your husband acted childish in this regard. At any point in marriage where you no longer feel comfortable settling your differences within yourselves. Particularly one that is not life threatening, then you are inviting devil to your marriage. Imagine his father came all the way from the village pleading for your return but your father insisted you should not return. After all, it is your marriage.

Finally in your best interest, it is important that you first forgive yourself because even by now I am sure you have hurt yourself in the process of trying to take revenge. He has begged afor forgiveness,and you don't want a divided home. It is evident even you have missed the father of your children. It is best in the interest of everyone that you return to your husband. Thus turn to God in prayer and seek His divine guidance.
