Diesel - hate to tell you this - but I believe that some states would consider you already married... I believe it's called a common law marriage...
There is something special about someone that knows all of your faults - especially the ones that you don't know about - and who still chooses to stay with you - regardless of what may come. Someone who will stand with you, even if the rest of the world is against you. Someone who will believe in you when everyone else tells you that you can't do it. There is also something special about making a decision to stand with someone, regardless of their faults and regardless of what life throws at them. This can not be matched by any form of dating.
The biggest thing that we've learned about marriage is that in the end, it is a decision. The people who divorced had to decide at some point to divorce. In our marriage, divorce is not an option - so we are forced to make things work - regardless of how we feel. Even if you find the "perfect" mate, she WILL irritate you at some point and you WILL make her mad at some point. Both of you WILL have periods of time where you wonder why you got married. If you follow your feelings, you'll get a divorce. Feelings are a fickle thing and are apt to change at a moments notice - that's why a firm decision and the commitment to stick with it are so important. I heard someone say that if you fall in love, you can fall out of it. Once you get past the initial attraction, love is a decision to stick by someone regardless of what may happen.
The important thing is that if there is no "escape clause" (divorce) then you WILL get through it and be better for it. If you're on a burning ship and there are no life rafts, you WILL figure out a way to work together to put out the fire. We've been married for close to 10 years and have had to put out our fair share of fires. Yes - there were times where we really wished that we had life rafts and we both wondered who had the dumb idea to ditch the rafts... but it has always worked out for the better.
By the way, am I saying that all divorces are bad? Absolutely not. There are some situations where it is the best option (i.e. an abusive spouse that refuses to change).
