[Ninastar]

Right, I'm sure a lot of you are aware of the fact that my dad has a gf who he is marrying (tomorrow, welp) and I'm still upset about it, but if it makes him happy, then I'll just have to get over it. But it's come to my attention recently, that she's been saying nasty things to my sister (who moved to his house a few days ago) and she's also been saying nasty things about me.

The next time I see my dad, he'll already be married, so I really don't know what to do. She's been telling my sister things like 'your sister is selfish and bossy' and 'you know your dad can't afford to look after you when we move to america' and loads of other little things. She doesn't work and my sister is looking for a job while she stays at my dads house, so it's pretty much just them two alone in the house until my dad gets back from work.

My dads gf has put up 'HOUSE RULES' in the house, because they are getting married in the states and she thinks my sister will be throwing parties and all this. When I was saying by to my dad on friday, I got annoyed and said 'Look, what kind of people do you think we are? We have never once thrown a party.' and my dads gf looked at me like I ****ing punched one of her cats.

My sister has to ask my dad and his gf permission if she wants to have one of us over. It's so pathetic. One of the rules even says 'NO ONE IS ALLOWED IN OUR ROOM', which is stupid because it's where the bathroom is.

Anyway, all that is pretty irrelevant. I just got stuck in rant mode.

Do you think I should mention to my dad that his gf has been saying really nasty things to my sister about my family? With the type of person that she is, I think she wants to have a big fall out, but shall I ask my dad about it anyway? My sister would be home at my dads house, so I wouldn't want her to feel guilty.

What would you do? I'm really unsure about this. This woman always has ulterior motives. I don't know if she's saying these things because she wants there to be a big fall out.
