Really, this depends on what sort of friendship you're talking about, and whose secrets you're sharing!
Sharing Secrets: When to Share and Who to Share With
- If you're close friends with someone, you probably trust them not to tell everybody else your secrets. If they've got previous - or have shared other people's secrets with you - then you might want to think carefully before spilling your own!
- I don't see how sharing secrets with a close friend could ruin the friendship in any way. The only way that might happen is if the friend then tells someone else, or is likely to share it with everyone if you two have an argument or stop being friends.
- If your secret is one that's likely to upset your friend, then it's probably best to keep it to yourself. For example, "I got drunk and slept with your ex-boyfriend" might not get a very positive response, but honesty is just as important in a friendship as trust is, so on the other hand, it might be good - in the long run, at least - to share a secret like that.
- Don't share your secrets with casual acquaintances or sort-of friends. This is often how gossip starts, and can quickly get out of control!
