MY WIFE KISSED ANOTHER MAN WHILE WASTED...DID I DO THE RIGHT THING? cannot break up, little kid involved?

You have not handled the matter as a nice man but as a novice. Marriage is based on Trust and Love. If either of that is missing the marriage will be a pain. Your wife has done something that you cannot trust her and it appears she has love for someone else so love also has gone. Now what is left in married life. Nothing. Now if you try to kiss her you will feel that somebody else's lips prints are there, if you touch her boobs you will find some body's finger prints over there and while having sex what you will feel only you can imagine. The life will be miserable as most of the time you will feel that you were cheated. There are many couples in the world who take divorce and their children also are taken care of and they grow up and be successful in their life. So don't punish yourself thinking about children. Study the local laws for divorce, consult a lawyer and talk to your wife also. If she agrees for divorce by mutual consent it is well and good otherwise you will have to approach the court of law for divorce.
