Cheating help?

My partner of 11 years recently told me he had been having an affair for a few months. He said it’s totally over now but I just can’t help but feel once a cheater always a cheater. I’m looking for someone to text him and act like they used to know him from the bar. I want to see if he engages in conversation with said mystery woman from his past. Is there a platform out there where I can find someone to do this?
