A few months ago, my younger brother R (19M) opened up about how our older brother C (27m) groomed him when he was a kid. It made me feel sick to my stomach, especially since my older brother would have been a legal adult at the time. I've since tried to minimize contact with C outside of family events without bringing up what he did, but he's incredibly persistent in including himself in my life. Every week he texts asking to hang out and I just keep saying no, but I'm worried that after a while he will suspect something is up. I've thought of blocking him, but that would be an even bigger signal that something is going on. I really don't want to be around him at all anymore, I just can't look at him the same.

My brother R says he doesn't want me to bring it up with C or our parents so as to not ruin C's life. I'm trying my best to respect his wishes by not rocking the boat, but I'm not sure if what I'm currently doing is feasible in the long term. Is there a better way for me to go about this or should I keep doing what I'm doing?

If anyone has had a similar experience, how did you go about it?
