I agree with the other wise, wonderful posters, @sarahsweets. You did nothing wrong! In fact you've been a WONDERFUL sister and you've don ALL you could do! Things like this are always hard because it feels like you're forced to pick a side even if that isn't the intention and that's not fair to you. I'm so sorry for what your brother has been through I agree with him that a therapist would be the wisest option. It seems like it took a lot of time for him to speak up about it and that likely made things more complicated. It isn't his fault though. We all process our experiences in our own ways and with our own time. Hopefully he'll be able to work on it. Hopefully he'll also be able to clear things up with your friend but the choice is up to them! Either way, please do NOT blame yourself as you're acting the best possible way, truly. Listening to him, validating his feeling, caring for him and making him understand that you believe him are really all the things you can do. The rest is up to him. Feel free to suggest but the final choice will be ALWAYS up to him. Please don't beat yourself over this. You're kind and sweet. I'm so sorry that you're feeling so bad and I hope things will get cleared up soon! Sending many safe, warm hugs to BOTH you and ALL of your family, sarahsweets!
