I once had a friend who did not take my advice this girl he liked gave a lot of red flags "just male friends" wearing revealing clothing wanted male attention when he wasn't around had a lock on her phone and did not give him the password He asked me what he should do because he thought she was cheating I looked him right in the eyes and I said "slap her or kick her out" he did not listen and even laughed at how wrong I was 4 months later he found out she cheated on him 5 times
