If you find yourself thinking about your potential sweetie with increasing frequency, take it as a sign that the obsessive, potentially destructive energy of this transit is getting to you. On the other hand, your obsessiveness could take a different form altogether: instead of talking openly and calmly with someone new, you could become intent on figuring out exactly who they are, and you'll pay way too much attention to the details and not enough to the overall picture they're presenting you. You might overanalyze a phone message or email from that special someone, wondering over and over, What did they mean by that?
Why would they say such a thing? This is the kind of problem that requires a little perspective (or a lot), the kind you can only get from distance or from objective parties who know you well. Get a good, trusted friend's perspective before you start freaking out. If you're obsessing over someone, feeling like your attraction is bigger than anything else that's going on in your life, take it as a sign that you need to step back and pay attention to something else in order to bring things back into balance.
