Cheating is cheating. If I were dating someone who confessed to a revenge affair, I wouldn't give a $#!t about the why. Instead of taking the high road, you are now a cheating hypocrite who's endangering the life of your children's mother.

You are potentially exposing your wife to HPV which causes cervical cancer. It's the most common form of STI and 50% of people will have it at some point in their lives. It can take two years for the virus to leave your system and may never manifest in physical symptoms. It can not be tested for in a STD screening, so your co-worker may have HPV and have no clue. Especially if she's willing to have unprotected sex with multiple partners. I doubt you've been her only partner in the past two years.

I'm surprised you trust that your co-worker has an IUD and is STD free. As your wife's infidelity should've proven to you, people lie everyday. Do not take someone's word that they are "safe". I'm so amazed that people still have unprotected sex with multiple partners in this day and age, so not worth the risk.

I do feel bad that your wife cheated, but holy moley I'm stunned you've sunk so far. Of course BS's ponder the idea of a revenge affair. It's popped into my head a few times in the year since d-day, but revenge is not worth my integrity.
