My mom (77) takes an annual trip out of state to visit my brother (58) and his family. The trip is the same time every year and she stays for about 5 days. My SiL does not like us. Never has. She never explicitly said so, but her behavior and attitude does.

For example, she constantly frowns, give short, curt answers when we try to strike up a conversation, or walk away like she doesn’t hear us. Little things like that. She and my brother have been married for about 30 years and my now deceased sister and (54) I gave up on a relationship years ago. Anyway, when my mom went a couple of years ago, she and my brother got into an argument and she told him that he could get the eff out and “take his mammy with him”. My mom was extremely hurt and upset.

When I heard this I called my brother and he confirmed it. The argument was a bit intense because I felt like he should have stood up for our mom. Anyway, I demanded that mom never set foot in his house again. I told her that if he wants to see her, he can travel to us. (Mom lives with me). FF to 2025 and she’s planning her trip, told me when she’s planning to go. I looked at her like she grew an extra head and told her that I wasn’t going to buy her round trip ticket and to get there the best way she can.

She bought a greyhound ticket and took the 16 hour ride. 🥴 I felt bad and paid for her ticket home. Mom won’t stop fussing at me for not buying her ticket in the first place, but says she enjoyed seeing the countryside. The SiL is still mean. Anyway, AITA for trying to forbid her from visiting my brother and refusing to buy her plane ticket?
