"The harder we work, the luckier we get"?+1. It is difficult to read the smug posts of those that have a long term relationship and attribute it to their own skill. As they say, it takes two to make a marriage, but only one to end it.
I don't know about skill, but I suspect a large part of marriage is having the benefits of the status quo exceed the hassle factors and risks of seeking other options. I'm not implying self-subjugation-- rather the shared interests that are easier pursued together than apart.
But her happiness is still important to me...
