Obviously, our friends are there to hear us out when we clash with our spouses, but if you give too much detail, be prepared for your friends, rightly or not rightly, to judge your spouse. If you're on the verge of divorce, it's another thing, but still, just be cautious, otherwise it can create a worse divorce process. If you're in an abusive marriage, please share that with your friends. But, in most cases, it's good to not divulge every vicious detail, and if you do, keep it to a few select friends.
