Sure, 50% of marriages currently do not terminate through divorce. However, some of that 50% is a result of the married man knowing he has much to risk, namely alimony and child support, if divorce occurs. He subsequently is less likely to initiate a divorce because doing so would fail a cost-benefit analysis. The marriage itself may not terminate even when the love has in such a scenario. One has to wonder how many of these 50% or so of marriages which do not end up in divorce actually are fulfilling ones.
