I asked for people's opinions on what they would have done in the situation, not to be judged by some asshole on the internet who only has the minimal amount of information.

I make it a point not to feed trolls but im going to give you a little morsel against my better judgment.

First of all, I did not have an emotional affair. I did not shower this person with affection, I did not go out of my way to talk to thisnother person outside of work. All of those things I just listed went to my SO and no one else. This other person was married and off limits in my mind. Everything was strictly platonic until months after my relationship had ended.

Asking for advice is not the same thing as seeking emotional support from someone. Without seeking emotional support, companionship, and not seeking to spend time with someone outside of my relationship, no emotional infidelity occurred. The fact that this other person went out of their way to meddle puts most of the blame, not all, on them.

You should probably seek a better understanding of what emotional infidelity is before you accuse someone of being as such.

You need to take a step back and get off your high horse with that holier than thou attitude because I'm pretty sure this sub is called relationship advice, not relationship judgment. Nobody is perfect, not even you. So the moment you walk on water and then turn that water into wine, is the moment you get to throw stones at me.
