There are going to be exceptions to every rule, and I am glad you are one of them. My point was that sometimes we overestimate our own ability to handle a situation, that is, until it actually happens. So when giving advice, it is always better to err on the side of caution than to presume otherwise.
I like to remind people that they are human, and that whatever it is they are going through or struggling with, they are no better or worse than the rest of us. That experiencing jealousy does not make you a failure at polyamory. That nobody should be ashamed of their emotions.
We make mistakes. We learn. We move on.
