@Sha2520032003 I hate this system so much lol I really love the pack but fated mate makes me almost not play it. It continues to ruin my weresims. Without mods, I've tried everything. I even had my Sim who has a child by her soul mate (that I chose) finally "fight fate" at the alter and marry her human fiancé thinking this would remove fated mate. It didn't. Now she's tense in her marriage. The one she's fated to is actually a sim she despises after a fight. And YET she's still tense when he adoring husband is romantic with her.
I eventually saved my other weresim and deleted him out of the game just to put him back in with rank and job still in tact but I don't want to go to that extreme every time. Even if it's me who changes my mind about "oh I actually think this is a better match" I want the option to get rid of fated mate. Like there's no free will here at all.
I'm not sure if mccc or ui cheats has a way to rid the relationship panel of this yet.
