Yes, no form of birth control is 100% but the lying is what makes this so bad.
Everyone knows that there is a chance of pregnancy if you use a condom or are on the pill. You weigh the risks and take the chances every time you have sex.
Psycholady wasn't playing by the rules. She lied and Puds couldnt properly weigh the risks.
I cannot even comprehend lying to someone about being on birth control.
Of course Puds is partly to blame, but psycholady is way more in the wrong here.
