My (26F) sister's (24F) behaviour towards my husband (29M) is horrendous

My sister and I have been close our whole lives, but she’s always been quite spiteful and has often said things designed to get a reaction. This is relevant context as it’s part of who she is, and has been for a long time.<br><br>My husband and I have been together for ten years and got married last year. He is a very kind, patient man who has always gotten along well with my sister. My sister was a bridesmaid at our wedding.<br><br>Over the last few months though, my sister has started saying things that are really hostile towards my husband. It’s always things like “I could never be in a relationship where my other half doesn’t do X, I’d never put up with that” (things like cooking, cleaning etc), and always says it right in front of him. She has also said things like “I would never do that to MY husband”. That sort of thing. She also often recounts things her boyfriend did that she didn’t like, and says how she made sure to tell him how wrong it was (usually in front of my husband), even though my husband wasn’t even involved in whatever my sister is talking about, to make her point. Other people have commented on this. Emphasised that my sister says all of these things right in front of him, and that she always makes her point by comparing herself to me and my husband in these types of situations.<br><br>My husband is a very easy going, quiet man, and he would never say anything back to her. He’s told me he feels uncomfortable because it’s always passive aggressive, but there’s no use responding to passive aggressiveness so he just lets it go. I have spoken to my sister about it, and all she ever says is that she’s speaking about her own relationships, and that if he’s getting upset over it, it’s his problem. I’ve explained to her that my husband doesn’t have a problem with her, and that she’s making him feel uncomfortable and disrespected with her comments, and all she ever says is that she can say whatever she wants because it’s her opinion. I’ve said “I understand you can discuss your opinions, but it’s over and beyond ordinary discussion, you’re deliberately going out of your way to make him feel bad, and you’re making me uncomfortable too by saying these things in front of me”.<br><br>She won’t stop, though, and there’s nothing I can say to her that will make her stop. It’s always aimed at my husband, too. She won’t say it to my husband, she’ll say it in front of him, like she wants him to hear it. I don’t know what to do, it’s becoming so frequent. It’s honestly gotten to the point where I don’t want to be in the same room as my sister now. It’s so stressful.<br><br>Should I just keep calling her up and asking her to stop? I have tried that, and she just hangs up on me and then doesn’t give me any opportunity to speak to her about it further. I don’t want to completely cut my sister out of my life but I’m starting to feel like there’s no other option.<br><br>I’m also 8 months pregnant right now and don’t want to risk any more stress or conflict than we already have as we are about to have our baby and we already know she’ll be a part of its life.
