What does she think about the whole Michael Jackson thing? I kid.
Anyway, this thread is making me glad I am happily married and not in the game anymore. 
It's funny you say that, cause this thread has me feeling a similar way, but I'm exactly in the opposite situation as you.
I am not married, not engaged, I am in a relationship, but it's not incredibly serious. By that I mean that everything with my girlfriend is very light and easy. I am finally at a point after going through a lot of relationships (and getting hurt in a lot of them) that I've found the right kind of balance. I really like my girlfriend a lot, and I don't know exactly how to explain it, but I know that I will never get myself involved in a relationship that has the potential to be consumed with drama or hurt me. At least not in this stage of my life.
In some ways I'm missing out on letting myself get completely and utterly swept up by someone, you know that kind of love that makes you so happy but also turns you kind of crazy. It's so satisfying yet makes you so uneasy. I think I've just finally hit my stride in knowing exactly what I want, and right now, that is to be happy to be with someone, but not pressuring myself to feel like the person i'm with has to be "the one." My current girlfriend fits into that mold really nicely.
I don't know, it's just interesting that we both had the same feeling from reading this thread, feeling great to be exactly where we're at, even though we're on opposite ends of the spectrum concerning our relationship status.
(C'mon, you have to admit you miss the good ol' days of being a bachelor, where anything could happen at any moment. Any chance encounter could turn out to be the most important moment of your life. Don't you...just a little bit?)
