Maybe he just isn't the type to want to get married? I wouldn't have gotten married (it took me 5 years to agree) if it weren't for not having any "benefits" without being married. Unless we are married, I couldn't receive his pension, health insurance, etc.

I love my husband dearly, but I was perfectly happy with things before. And, for me at least, things are the same now, so there really wasn't a "next level" to things.
