I often talk to my spouse as we dated and early on in our marriage that “if you ever cheated on me, I will have the right to cheat on you”. My spouse agreed to this. I found out my spouse has been secretly communicating with an EX for 14 years (mostly emails and one phone call). It’s flirting emails so it’s emotional affair, we agree. I’m now have the right to cheat. My spouse agreed to let me have a fling/one night stand. I want to have a one night stand but afraid if it turns to be more. What if I can’t let that person go? What if I really like that person more than one night stand?
