I cheat on my wife with other men.
Do you still want to be with your wife then?
Yes, but I want more than she can give me.
It sounds like your marriage isn't really fulfilling your needs but that doesn't excuse you cheating on your wife. You have to stop the cheating or separate from your wife.
Why should I stop, I want to be happy.
If you do not want to stop, you should at least leave your wife so that you do not hurt her. It is not okay to be cheating on her!
