I believe the player should be able to get married whith the married NPC's and they get divorced from who are married.
i think it should be possible except if the married couple already had children and if they do then have the children live somewhere else seperately and the ex would still live in their previous house but doing so would make the ex never speak to you again and have negative reactions for the children of your new spouse
Umm.. that is called an affair. People are not fans of affairs sir. Cuz that totes aint right yo. I mean, how would you like it if someone tried to move in on your gf/wife/hubby/bf? Youd probably pop them right in the noggin but good. Basic relationships 101 there.
I mean, if you like Caroline you can marry her but Pierre sells you seeds and these tuff at higher price and he hates you, if you like Gus he gives you some good food like pizza or spaghetti.
