I know that roughly half of first marriages end in D, and around 70+% of second marriages do as well.

Questions if anyone knows:

1. Does that stat continue to increase for third, fourth, etc?

2. What about for marriages where it's one spouses first and one spouse's second? Is it considered a 2nd marriage for research purposes?

Is it more likely that a spouse who's been previously married will be the one to initiate a divorce...or is there research on that?
