Input: Hey all, sorry if the answer seems obvious, but I'm kinda tangled up in thoughts here and would love some advice.

So I (22F) recently came to the realization that my brother (24M) molested me several times when I was between the ages of 10 and 13. Currently, the only other person who knows is my boyfriend, since we started dating just as I was figuring all this out. So here's the dilemma:

I feel like this is something that I need to talk about, and that the people who care about me should know about. However, it would be absolutely devastating to my parents (especially my mom - she recently wailed and screamed at my brother for cheating on his gf, so one can only imagine how she would react to this). Furthermore, my brother is already on rocky terms with them, so it has a very real chance of destroying their relationship with him. As important as it feels to me, I can't help but think it would be selfish to prioritize my comfort over their happiness. 

I should note that my brother has recently apologized (though he might have been blackout drunk) for one incident that happened when I was 10, but hasn't acknowledged any others. To be honest, it wasn't the best apology, and I'm not sure if I'm ready to forgive him, but that's beside the point.

I love my parents so deeply, and I don't want to burden them or taint our family dynamic, but this is really weighing on me and I can't stand withholding something so important from them. WIBTA if I told them?

PS: I haven't seen a therapist about this yet because lol @ my university's mental health services, but I have no intention of telling anyone else until I get some professional advice. There isn't exactly a handbook on handling these things, so any advice or reactions are welcome. :)
