I’m a teenager with a very close but complicated relationship with my mom. She and my dad have been married for 25 years, but their relationship has been nonexistent for the last 10 years. My mom believes my dad cheated (though there’s no evidence), and since then, she’s been extremely vocal about how much she dislikes him. She constantly complains to me about him, which has affected my mental health. Fast forward to now, after struggling with depression and starting therapy, I’ve realized the way my mom talks about my dad has been unhealthy for me. This year, she planned a city trip, expecting me to go with her after her friend canceled. I don’t want to go, both because I’m not a fan of the city and because I’m exhausted from hearing her complain about my dad all the time. I tried to express this nicely, but when I suggested she go with someone else, she got really upset, calling me ungrateful and a bad daughter. Now she’s saying she’ll go alone and telling my brother I don’t want to do anything with her. I feel guilty for disappointing her, but I don’t know if I should’ve just sucked it up and gone anyway. AITAH for telling her I don’t want to go?
