Break Up & Divorce

What is the most creative way you have caught a spouse cheating?

My wife, She works in insurance. Toward the end of our marriage, she started doing these three day weekends for "work" With her boss at insurance conferences. I started to get suspicious mostly because she would behave evasive when i asked about it. So during one of these, i felt i should surprise her at her hotel. When i arrived at her room, she opened the door and acted surprised/scared, but then suggested we go out to dinner. She went to get a shower, i went through her toiletries and found an open, used box of condoms, Condoms which we never use because i have had a vasectomy. So, I took a safety pin and put holes in each one and put it back. We went to dinner, and i had arranged a phone call to come in with an emergency that would force me to go home. I kept doing this every time she bought new condoms too.

Later on, the affair partner's wife figured out who i was and found me to confront me. I explained to her that i knew what was going on as well. We agreed to share evidence, which included recorded phone calls, videos, photos, phone records, text messages, and so on. Later on, i found an appointment slip for a local family planning clinic that specialized in abortions. I went to said clinic as the concerned husband, and they made me sign a consent form confirming that i am the husband. From there they explained that the appointment was for an abortion, which would happen in about two weeks. That weekend we went with her sister and her sisters husband on a fishing trip, I ended up not going fishing and staying around. Her and her sister were angry with me over that. It was then when i shared all of my evidence, explaining that i knew what the appointment was for, the safety pin, and everything else, With divorce papers. I explained that if she wanted to keep this quiet, she would sign the papers and disappear, if she fought me, all of the evidence i had would go to everyone she knows. She signed, and moved out.
