Eeka Mangi,
I am trully sorry for your awful situation. As some said hapo juu God loves you and that is why HE revealed all this to you.
What I can say Brother is that nenda kaombewe, all those hirizis and what not are not good. If you are christian tafuta pastor to pray over you so that the shackles of darkness maybe broken. They are a sign of the times, though. People do not want to work hard, they want easy, example ni kama huyo "uncle", collecting money from your wife and driving her car. Some one once said that it is the new Job description, a kept man. As for your wife, I feel sorry for her...She got greedy too!! she wanted to have a cake and eat it. So far in life no one has managed to do this, have the cake and eat it. They are always found out.
Usife moyo, let God direct your footsteps.
