As I said in the earlier thread on this page, married women in Regency England were highly dependent on their husband's character. They lost control of their money (unless their family took particular steps), they were subject to his decisions, it was pretty much impossible for them to obtain a divorce. Even nowadays I have seen a marriage to a conster or a gambler or a drunkard cause a lot of misery before and after the divorce (regardless of the gender of the person in question), in Regency times the misery could last for a lifetime.
