Dear Prudence,
My husband’s ex-wife was emotionally and physically abusive and cheated on him multiple times. He stayed for 20 years because of their kids. They’ve been divorced for six years, and we’ve been married for two now. Before they got divorced, my husband’s ex hadn’t seen anyone in his family for almost a decade. For some reason, my brother-in-law’s wife and my sister-in-law’s husband are still friends with her on social media. I didn’t think much of this until I recently noticed that they comment on each other’s posts and photos. It seems like a betrayal of my husband, since they know everything she’s done to him. It upsets him, but he doesn’t think there’s a point in bringing it up because he thinks it just shows that his family doesn’t care about his feelings. His parents and sister have been open about disliking her since they separated. I just don’t understand why they feel the need to stay in touch with her, especially since they weren’t close when they were married.
How should I handle this? I seem to get along with them fine, but this makes me question that. We don’t see them often since they live pretty far away, but I try to make sure we send cards for birthdays and holidays and that we see them a few times a year. I just don’t know how to support him because my family would never do something like this.
