What happens if you love someone, but...

AllyMay’s excellent question about marriage prompted me to ask this question. Great question, Ally.
What do you do if you feel strongly that you want to be with someone for the rest of your life in a monogamous relationship, but you feel like you met them “too soon”. Meaning perhaps you thought you would have a few more “wild” experiences before settling down with one person. Obviously you have to choose between how much you love the person, and how much you want to be “wild and free” but as some wise flutherer recently pointed out (was it nikipedia maybe?) what are the units? “love” and “freedom” are not measured in the same units. It’s like apples to oranges. How does one go about making that choice?
It’s a theoretical question. Answer it any way you see fit.
