I'm worried that I may be overzealous with my current situation. Background: I've been friends with someone for over 10 years. The rub is she lives in Iowa. But she wants to see if a relationship can bloom. We're making plans to meet up in May (I'll be going there). My concern is that I'm feeling smitten, and quite quickly. Am I being overly cautious feeling like I'm getting too attached too quickly?

Do I just ease up and let it take its course?
