I totally understand what you mean!I'm in the same boat as CF_Gal. I do have a best friend, but she's lives in my hometown so I feel like I'm missing out on the experience. We've been bfs since we met, freshman year in high school-so, 10 years. We've changed a LOT over the years (she's engaged with a 4 year old and I'm the opposite), but we just kind of adapted to one another.
However, I am a firm believer that you can have that sisterly bond with more than one friend. I read an article that really made sense a few years ago (
this one is similar to it), and I'm still looking for those other amazing friends. There are different ways to bond with people. I've tried over the years to be close with "casual" friends, but you have to be careful who you choose. Sometimes, people really can't be trusted.
I would say that my boyfriend (3yrs) is a best friend too. He knows more about my everyday life than she does, but she knows more about who I am personally. Still, I wouldn't trade either for anything in the world!
