I's sick of my fiance's friend. I'm going to to give her an ultimatum. Either drop her friend or we're done.
Is it really so serious that you need to give her an ultimatum?
Yes! Her friend is a fucking stalker. She badmouthed me to her over three times already.
Not liking her friend is fine and you should be able to tell your fiance that but giving her an ultimatum is not good. At the end of the day, it's her friend and you shouldn't tell her who she can and can't be friends with. How would you feel if she did that to you?
Whatever, I've been a good fiance until she been friends with this ugly pig.
If the friend has been badmouthing you all this time and yet your fiance still wants to marry you, that just tells me your fiance knows better. I don't think you need to worry about a thing. Your fiance is more on your side than you think.
