What if your wife don't want to divorce you what will you do to divorce her?

You will have to sue for divorce. Get a lawyer and go through the court process. If both people want a divorce, it can be settled out of court without hassle, but if one doesn't, then it gets messy and expensive. Hopefully you don't have children involved, it would be even worse for them. In the case of children, I would suggest working it out for their sake so they don't grow up in a broken home.
