For some context, my sister is dating a guy who’s a lot older than her. I’ve never liked him—he’s selfish, doesn’t treat her right, never gets her anything, and honestly just seems like a bad influence. He’s also had a lot more sexual experience than her, which makes me even more uneasy.

One day, we were at the park, and she pulled me aside and told me he had sexually assaulted her. She said he kissed her multiple times without her consent and made her touch him—specifically made her stroke his dick—even though she didn’t want to. It completely broke me. I’m not someone who cries or shows vulnerability easily—I usually keep everything in—but I cried for her. I felt sick and heartbroken that she’d gone through something like that. I told her to block him, and she did, or at least pretended to.

Fast forward a bit, and everything slowly started to unravel. She never actually admitted she was lying, but it became clear something was off. She unblocked him and, literally two nights ago, when I asked her what she was doing, she told me she was going out with him. I was like, What the fuck are you talking about? And she kind of danced around it, saying things like, “Well…” I cut her off and said, “Keep your shit straight. Did it happen or not?” And she goes, “It did. Like, he crossed a lot of boundaries. But I don’t think he understood me right.”

It hit me then that she probably said it all in the heat of regret—maybe to avoid judgment or because she was scared I’d snitch or something. But she let me believe something incredibly serious happened to her. She let me cry for her, rage for her, worry for her, protect her—all for a story that now feels twisted and false. And she still won’t admit it.

I haven’t been able to speak to her properly since. I’m angry and I feel betrayed. Not just because of what she said, but because of what it meant—for her, for other survivors, for me. I feel like she used my emotions against me.

So, AITA for not forgiving her and not being able to just act like everything’s fine?
