How do I break the habits that keep me from finding Mr./Ms. Right?

Some very good advice from grumblebee:

It's NORMAL to have 4 or 5 relationships not work out. It's also normal -- but often wrongheaded -- to look for some sort of deeply-meaningful pattern in the botched relationships. Of course you're going to look for a pattern. You feel powerless, and when people feel powerless, they look for patterns so that the universe doesn't feel so random. So that it feels manageable. "If I understand it, I can do something about it."

Here's the REAL pattern: for MOST people, their first 4 or 5 relationships don't last. A introvert will think, "It's because I'm too introverted." An extrovert will think, "It's because I'm too outgoing." An overweight person will think, "It's because I'm too fat." An honest person will think, "It's because I'm too guileless." And their friends (and sisters) will think these things, too, because they are also looking for patterns.

This goes back to a principle of mine:

Don't make a global change when a local change will do.
