You get over the abandonment that law or laws has nothing to do with your divorce now.

You merely file for divorce in the county in the US state where you live. Most require no reason for divorce. Since you don't know where he is, the court will require some attempt to find him, and then notice in a specific newspaper of the divorce hearing.

Just hire a divorce lawyer, this is a common divorce where one party does not know where the other is.

And it is just a divorce, there is no such thing as "international" divorce. Once divorced here, you are divorced and can remarry
