RE: Marriage licenses are given by States, send it back to them.
So, what happens to a gay couple who were married in California and decided to move to a Red State that does not recognize gay marriage?

In the Red state they are an unmarried couple. Which isn’t a problem for a normal couples because all states recognize a 1 man 1 woman marriage.
Then they aren't considered married and can't take advantage of any legal protections that marriage provides. Pretty clear.
