You're not alone. I never really had a "best" friend in life until my boyfriend and I started dating. I consider him my first "best" friend, defined as an individual outside of my family who genuinely wants to get to know me and support me to a deep level. I have a few close friends that I'd consider "good" girl friends I hang out with and talk to regularly and have fun with, but they're proven time and again that they're not always there for me when I need them. It makes me feel unappreciated, because I know that whenever they needed me I was there for them...
