Not at all. The divorce system is NOT a pain from the female side - it's filled with incentives. The only way this could be a deterrent is to get rid of the "no-fault" divorce. Let the person who strays, leaves, or creates a hostile environment for the spouse pay.
The way it is now, women more than likely get custody (and therefore child support, whether or not it goes toward the child's benefit), a LOT of property (usually including the house, especially when there are children), plus alimony (whenever they can). That's quite a benefit package for the unfaithful woman.
For the unfaithful man... There's the poor house.
Hardly, but it is a potent deterrent to marriage.
Not when it isn't a pain equally for both parties.
As it stands now, it is a detterent for men to marry.
Make it so that men and women have an equal chance for custody, an equal chance of having to buy the other person a house, and an equal chance of having everything you worked for looted by the angry other person and I'd love to see how women as a group react.
