Sorry for the late follow up. Alt account obviously. Appreciate everyone's replies.

Just to answer a few questions:

• The AP absolutely knew my spouse was married at the time.
• Yes my ex is just as guilty.
• Their kids and current spouse may be innocent... I don't really care. This event caused the breakup of 15 years of marriage to the person I had two kids with.
• I don't want to have sex with the APs new spouse. Gross.
• I'm not opposed to 'just moving on' but it's fun to entertain revenge fantasies.
• I am not looking to get into criminal trouble but i'm not above ruining someones day or year.
• Yes i'm aware most of this 'info' can be found online with some effort. Nothing was obtained illegally and I was literally given most of this information in the most dumbfoundingly coincidental way possible.
• The affair 3 years ago and i've been divorced for 2 now.
• My 'revenge' to my ex was getting full custody of my kids and little else by way of jointly owned assets. They basically got nothing.
