"When someone shows you who they are, believe them the first time"

This quote from Maya Angelou is often thrown around when it comes to infidelity and I just want to say I HATE IT!!! By the logic of those who use this quote to respond to a betrayed partner looking for guidance, we are supposed to throw away the loyal and loving partner we had for years (in my case almost 20 years) because their affair was "who they are"?! They were an amazing partner for years/decades, but THIS is who they are?! I don't think so. Sorry, they showed me they are a truly GOOD person "the first time", and that is what I will continue to believe.
