I’m feeling quite disappointed and would appreciate some opinions.
My sister (10 years younger than me) and I have always been close. A few years ago, she started dating a woman, ‘Abbie’, and I became friends with her. We had a great dynamic, often hanging out and even going on holidays together. No dramas or arguments—just supportive relationships all around.
In June, my sister began telling me about controlling behaviors from Abbie, which sounded borderline emotionally abusive. Abbie pressured her into getting a credit card in her name because Abbie couldn’t due to debt, and she would guilt-trip my sister for going out with friends, accusing her of cheating (which wasn’t true).
I fully supported my sister, telling her that the relationship seemed unhealthy. I distanced myself from Abbie as her treatment of my sister put me off our friendship. Things escalated in August when Abbie got angry about my sister going out with work friends, leading to a breakup. My sister was devastated, so I took her in to my home, gave her emotional support, and told her she was better off without Abbie.
Fast forward to now: my sister has been seeing Abbie again without telling me, all while still sharing stories of Abbie’s toxic behavior. I continued to support her, expressing my concerns about Abbie. But unbeknownst to me, my sister was relaying everything I said to Abbie, making it seem like I was randomly bad-mouthing her, ignoring the context. Abbie called me angrily on Monday, and now my sister is siding with her, portraying me as a troublemaker. She’s moved back in with Abbie, and we haven’t spoken since.
Am I unreasonable to rethink my relationship with my sister? I feel like all my care and support have been completely disregarded.
Thanks in advance.
