Answer 1

I know this sounds weird. are they actually blood related? Do they have one of the same parents? If not, then technically they aren't doing anything wrong. Is it weird ? Yes. However, you need to talk to your boyfriend about this. Tell him how you feel and how uncomfortable this makes you. Explain that you would prefer that she didn't spend the night. If he refuses to understand, then you have a bigger problem than having the two of them sleeping together. Good luck.  

Answer 2

First of all, that's kind of creepy.  Second, tell her that it's creepy and that you don;t want your child to grow up in that kind of situation, if she's offended, tough.  

Answer 3

Hello x)

The only thing you can do is TALK, yes talk to your husband first of all and ask for his opinion to see what he thinks about the whole situation maybe by talking to him both of you guys can talk to his brother and his step- sister, like you said is your house and they should have some respect for it...

Best of luck!

Answer 4

Well are they still step sister? Did the parents split up? Did the parents get a divorce? Because if that is the case, then technically by law they are no longer family. You could ask your fiance, to talk to his brother. Brothers tell brothers everything..!!
