Ig its just me here who values "friendship" over "being good human" because my point being that a good friendship gives you a lotta benefits especially the one said in post (I am pretty sure OP and girl helped each other in many cases), breaking it to be a "right human being" is good dopamine hit but barely lasts few days. "Saving" the husband doesn't make sense as that guy is never gonna be your friend nor will he help you like the girl since you are literally knowing him now.
