Oh for sure. Unless the other person has lied to you about it, getting into a relationship with someone who’s married with a new baby is not ok at all. It’s just the narrative around this seems to be “Ariana the home-wrecker”, not “scumbag husband and dad destroys his entire family”. The person in a relationship who chooses to cheat will always be more liable/guilty/detestable in my book. Even if it like choosing what’s worse to step on; Lego or dog shit.
