I hear people sharing their problems with their friends all the time, and yes friends are supposed to be there to support you, but there is such as thing as being too open. I've heard people telling their friends that they cheated on their husband, gambled away money their spouse wasn't even aware was there, contracted an std traveling and don't know how to hide it from their gf, etc. Sharing that just makes me question your moral character and whether or not I want you in my life anymore. Sometimes less is more, and it's better to be a listener than a talker.
