Actually, I've looked into this pretty recently myself. 70% is a slight exaggeration, but mid 60% is the national divorce rate. However, where varus' homework fails is that women initiate more divorces because married men are more likely to cheat (or arguably, be caught cheating). Other reasons for divorce include abuse, alcoholism/drugs, gambling addictions, and simply avoiding discussing relationship problems... all which are more likely to be the man.
Assuming varus already knows this, he's just ******** that women don't put up with as much ******** as they used to. If they're to blame for anything, it's marrying the fool in the first place.
Personally I just don't think marriage means anything anymore, if it ever did, no matter how you slice it. Any promise in your early life to feel a certain way about someone in your later life is a lucky guess at best, and at least an empty promise. I think if anything, a greater testament to your commitment to someone you love is to not marry them and still wake up beside them every day... having every option to walk away and not doing so. Frankly, the thought of marriage, or rather, the prospect of divorce, being the thing that keeps two people together disgusts me a little.
Which hardly makes my partner happy, but she gets it.
