For what it's worth, I relate to this a lot. I recently got married to someone after knowing them about a week. I am constantly taking ridiculous trips, leaving one man to pursue another, shifting my 'mission' and passions in life from one thing to another. "Insatiable" is a word I've heard often as well Personality or illness? I don't know...I don't see these as separate parts of who I am.

Are you feeling a sense of urgency in making a decision one way or another right this minute? My suggestion, despite the desire and impulse to do otherwise, is to establish a timeframe and wait it out, see how you feel in a month? 6 months? "Logic" and what "feels right" aren't anymore permanent than your moods...you are aware that you change your mind frequently - why not take this crossroads as an opportunity to try and do things differently? Obviously don't marry someone who doesn't fulfill you. But if you truly don't know whether this is actually the case or if it's part of a mood that will pass, then I wouldn't make any hasty decisions you might regret.

Of course, this is all easier said than done. I'd probably be half way to Mexico if I were you :/
