All she has to do is get a divorce and then they're cool. A recent YouTube video got me down the marrage to first cousin rabbit hole and it turns out that social norms are WAY more strict than the actual law on that issue. https://en.wikipedia.org/wiki/Cousin...tates_by_state
EDIT: Don't even have to get a divorce, marriage is void if first cousin. Scroll down to the chart.
