Breakups are Hard

Recently I have had to breakup with a hairstylist and a friend, both at the same time, and it's not the same person, so it's double the predicament.
Breaking up with my hairstylist only makes sense since Lauren is able to cut hair now. It doesn't make it any easier though. Why do we girls get so conflicted about this? I feel disloyal and feel bad that she will lose a client, but she had to see it coming. She knows Lauren is in cosmetology school. I've mulled this over for months now and decided that I will go see her one last time then it's over. We will have to go our separate ways. I think I might design a greeting card for just this occasion, I could make a fortune.
The second breakup isn't so easy. I recently made an observation about myself. I tend to have friends that suck the life out of me. I guess I finally had the nerve to admit it or I have enough good friends around me now that it became more clear to me. I also felt conflicted about this but realized that we all change, grow, and become different and it's OK to move on from a friendship that isn't really healthy. Friendship is a two-way street and if all the signs change to one-way, it's time to find a new route.
