My 30th birthday is coming up and for the past six years, I've been living a fabulous single girl life. However, with more and more friends getting married, moving in with their boyfriends, and having kids, I'm starting to feel isolated from the people I'm most close to. The thing is there are several interesting men in my world and while I have fun with them and am compatible with them, there is, as Carrie Bradshaw said, "no za-za-zoo." I don't feel that special butterfly feeling where I really like a guy. In the past couple of years, I've only felt it for three guys and the last time I felt strongly for someone was months ago. I'm starting to worry that maybe I won't feel that way again and perhaps, that I'm waiting for something that will never come. Should I keep waiting? Or try to pursue a more meaningful relationship with a guy that I enjoy and feel comfortable with, but don't have a deeper longing to be with?
