Should I tell her
My brother had a girlfriend that I genuinely really liked. They recently broke up because he was toxic toward her he called her names, including a b****, mistreated her, and cheated on her. She forgave him more than once, and even after the breakup she has continued checking in on him because she cares about him.
They are still friends and have been hanging out. She called me recently and told me they are still hooking up, even though they are technically broken up. The problem is that I know my brother has also been sleeping with other girls.
I feel conflicted because I don’t want to betray my brother or create more drama, but I also care about her and don’t want her to get hurt or put her health at risk. I don’t know if she thinks they are exclusive again, but I feel like she deserves to know enough to make an informed decision.
Should I tell her to be careful and get tested, or should I stay out of it? If I do say something, how can I do it without making things worse?
