AIBU?
My sil is a complete bitch. She seems to be jealous of my dh and tries to stir it when she can. Before I even started going out with dh I remember him telling our group of friends that she'd phoned him from abroad to tell him to either get out of her flat or buy it off her/sell it within 6 weeks - he was a full fee-paying guest! Parents don't know she was going to throw brother/dh out.
Now when we go to visit parents she always manages to turn up with her brood. She's lied about who the father/s are - keep it to yourself, dont go round telling every family member a different story. She announced one of her pregnancies when we were there on holiday - devout parents horrified and v. angry = baaaad atmosphere + lovely holiday for us! She twists and lies about anything I say to MIL who always sidles up to me and says "SIL says you said dah-dah-dah, is that true". Any time she phones she goes on and on about the money she gets from the father/s as if the kids were just a money-making enterprise! I could go on ,she's a horror. There's just so much the family don't know about and she annoys me so much. Any advice?
