So my girl and I...
have been together for several years. My sister is 22 acting wild and crazy, even for her age. We work together and live in the same apartment building, so aside from being her older sibling, we have a lot of other mutual squandered acquaintances and coworkers, so I find that her actions end up reflecting on me a lot. So when she gets too wild, I’ll chime in and talk to her. Anyway, this time my girlfriend had a different opinion. She agreed that my sister was acting out of line, but not that I had a right to say anything. So she went behind my back in a public setting and told my sister basically to disregard everything I said and literally told her to say “fuck them” to the things her friends and family are saying to her because she’s an adult and her decisions don’t effect us. But they do, from her not paying the phone bill in my name to the slandering of the family name. She looks a lot like our middle sister, like they could be twins, and people have mistaken them for each other and tried to beat this quiet single mom up. Her actions effect all of us. Anyway, my point is, it’s caused a huge fight between my gf and I. I told her I feel like she undermined me and that she should be unfailingly supporting me when it comes to my family. Her argument was that I was telling her she couldn’t have an opinion, which I countered with that was something she should be sharing with me and we could discuss. But she told me I’m wrong and until I change my views we’re going to have a problem. Am I wrong here? I just want some neutral opinions
