Hypothetical scenario for you, which I've found myself in.
You make a friend and over a number of years become fairly close but they don't talk much about their past.
You then find out that this person was sent to prison for the rape of a woman some years before you knew them.
You had no idea they were that way inclined and now question your own judgement, understandably you look at them in a very different light.
Would you instantly go no contact and cut them off on the basis that they'd commited that crime? Would you tell them exactly why you no longer wanted to know them?
Or could you stay friends with somebody you knew was capable of such things even if they'd always been a good friend to you personally?
More of a WWYD really.
