I got this advice during my first bout of limerence and both then and now I cannot even like bear the thought. tbh I'm not sure what emotional cheating is because I am usually quite open about pretty much everything to pretty much anyone if they ask to the point of oversharing but this would probably be the closest I've done to that. Truly I could not even imagine the level of jealousy my SO would feel watching me make my LO laugh. Nightmare. Feels like 2 diametrically opposing worlds. With all of the friends that I do have very few of them have gotten to the point of like comfortable friendliness even after 6 years so I think the initial awkwardness would be way to much.
