I have namechanged as embarrassed by my attitude! My much younger sis is a massive flirt, she is also stunning & by her own admission loves attention from men & says that she gets on better with men than with women. She has a habit of pointing out my faults, weight issues, grey hair etc & generaly stamping over my confidence. she gets on famously with my dh, he loves her company, finds her easy to talk to & she is always flattering him, telling him how good he looks, taking time to listen to him & monopolizing him at family events to look at his watch, learn ALL about his phone etc.
when he's not around she's her usual grumpy self but lights up when he walks into a room. She will criticize my musical tastes but when dh plays the same band/genre etc she says she loves it!! When I challenge her on this she denies she ever hated it!!
She shows little or no interest in our dcs but when dh is holding them she suddenly has a renewed interest and bends over to play with them and pretty much shows all of her ample boobs!
I know it sounds petty but we hosted a party where she she danced closely up to dh shaking her boobs in his face and not breaking eye contact. I was 8 months pregnant at the time and felt really weird about it..... Later that week she criticised somebody else for dancing in exactly the same way all over another man. I nearly reminded her that's how she danced to dh but I didn't want to make a scene as I know she'd downplay it and I also feel that she'd like a reaction from me.
Its getting to the point where I'm starting to dread any family get together as I don't know how to handle it..... Dh can't see a problem & I'm pretty sure he's flattered by the attention of a sexy young woman. we all do family things like swimming with all the kids, beach etc but I don't like going anymore because I can't relax because she always wears as little as possible! Honestly wherever we go she has every single man in the venue looking at her & cultivating!
I also think she knows what she's doing as she's very jealous in relationships which is why she prefers to stay single!
