It's difficult for you to figure out what you want in terms of a loving, committed future with someone special. You know that you do want love in your life, and intimacy; but with whom, and when, and how to go about making it happen, are all mysteries. You might feel like your future path precludes you from committing to a lover.
Perhaps you have a job that makes you move around a lot or spend long hours at the office, and getting deeply involved with someone just doesn't seem possible, much less fair to them. Whatever the source of your confusion and inhibition might be, it constantly seems as if your timing is off. You're holding back while your lover is pushing forward, hoping for a commitment; and just when you get up your nerve to say, Yes, let's take that step -- they've lost faith that it's going to happen, and they've moved on to someone new. This type of indecision can really hold you back from making things happen in your life. What are you afraid of? If you're afraid of heading in the wrong direction or making a mistake in the game of love, just remember that even mistakes can be helpful; at least they're movement, instead of stagnation.
