I haven’t been able to sleep and have struggled with this for a couple of weeks.
About a month ago, my brother went through a messy breakup with his fiancé, who I had been good friends with. Throughout the breakup, I gave him all the support I could—time, emotional support, even financial help to cover moving costs. I spent several days helping him move, all at my own expense because he was struggling financially. He relied heavily on me emotionally, even though I was going through a difficult time in my own life. Despite barely having the capacity, I did my best to be there for him.
During his lowest moments, I spent hours a day listening to him, offering advice, and trying to lift his spirits. He confided that his ex had been saying hurtful things to him and had even cheated. I supported him through that too.
Then, about a month after the breakup, they somehow made amends. Out of nowhere, I received angry messages from his ex, accusing me of badmouthing her. I found out that my brother had told her I’d been talking badly about her, claiming he’d defend her against me. He also told her that he had told me they were back together, and I had been trying to convince him to break up with her again. This was completely untrue. I’ve gone over it again and again, and the only reason I can think of for him making this up is that he was trying to show misplaced solidarity with her—“My sister hates you, but don’t worry, I’m on your side”?
When I expressed how hurt and confused I was, he gave a half-hearted apology, admitting he shouldn’t have done it. But he still didn’t come clean to his ex, and instead continued to paint me in a negative light. I feel so betrayed. After all the support I gave him, he just threw me under the bus for no reason.
It’s been a couple of weeks, and I don’t feel any better. My gut tells me to distance myself from him. He did this at a critical time for me at work, and it’s impacted me deeply. Am I being unreasonable to think about creating strong boundaries with him—or even cutting ties completely—despite how close we were?
