How do you listen to your subconscious mind?

First off, Is the subconscious mind the place that tells us what we really want in life? I ask because I'm caught between a few major descions, and I'm trying to figure out what to chose and what I "really" want. On the conscious level, I always teeter totter between my wants. I think I want one thing, and then I re-ess and think I want the other. I want both of something, and miss one if I chose the other. (basically I have a relationship descision) How can I find out what I truly want, what is my best choice, on a sub-conscious level?
