A best friend is invaluable, especially for women. Yet friendships are wrecked every day for reasons easily prevented. The following top 10 mistakes that wreck a friendship were gleaned from more than 16,000 essays submitted in the No nonsense® Between Friends Contest. For more information, visit www.nononsense.com.

1. Failing To Share. In the movie, The Women, a group of iron-clad girlfriends debate whether to tell their friend her husband is having an affair. In the end, the girlfriends' code of friendship prevails. A best friend always shares information even when it may be tough to tell.
2. Letting Life Get in the Way. A BFF break up is inevitable when friends don't hit key milestones in life at the same time, like getting married or becoming a first-time mom. Best friends recognize the difference between adding a role and replacing one. As women age they wear more hats and BFF's become even more important.
3. Forgetting Vital Stats. Missing or ignoring key moments in your best friend's life, like birthdays, holidays and special occasions, can be seen as disrespectful and may even signal that what's important in her life isn't meaningful to you.
4. Failing to Repay. Anything you borrow from a friend, whether money, a rake or her perfect little black dress must be returned … quickly and in perfect condition. If not, expect to replace it.
5. Being Boring. Even though friendships take work, they should be infused with fun. Enjoy each other and find the common ground that forms an uncommon friendship.
6. Allowing Men in the Mix. Whether you have a crush on your friend's ex or you're convinced her new beau is a bad boy, allowing a man to come between friends is inevitably a friendship buster.
7. Refusing Help. Friends give and take, and it's just as important to take as to give. When friends refuse each other's offers to assist, you forfeit an opportunity for someone to earn warm-fuzzies for helping.
8. Helping When You Shouldn't. Although you should do everything possible to keep your friend from harm, sometimes the best thing to do for her is to let her hit rock bottom and fail. Once in awhile, you need to provide tough love and hope she'll thank you for it in the end.
9. Gossiping. When you don't stick up for your friend or engage in spiteful gossip behind your friend's back, friendships are ruined. Show your friend you have her back -- always.
10. Acting Narrow-Minded. People grow, evolve and mature over time. Sometimes they even experiment in life. True best friends stand by with patience to stand the test of time.
