"My cousin has four girlfriends at the same time"

From a male blog reader:

Hello. Basically I am this gentle introvert guy. I mind my own business and work with my hands. My cousin and I stay in an apartment we rented together but I have really not been liking what he has been doing. He has 4 different girlfriends all madly in love with him. He has a perfect scheduling for them and each girl has never clashed in his place or knw they r nt his only gf. But each time I see these girls in our place, cooking, acting wife material, I really feel pity for them. Most times, they even ask me to bring my clothes, they wanna wash for me….Which i swiftly decline all the time. When you are not my maid. These girls r really nice and my cousin does not deserve to be doing this to them. Literarily, these girls r siting on a time bomb and completely have no idea. I see them and see somone’s heart abt to be broken. I cant really stand it anymore and I have decided to tell them. But I av two questions…. I know guys will particularly frown at this but I think what is wrong is wrong. 1. Should I tell the girls or continue to mind my own business. Will that not be me betraying my blood(my cousin) 2. If yes, How do I tell them without any evidence leading to me whatsoever from my cousin that I am the one who told them.
I really cant stand how very nice girls fall into the hands of devils. Sorry cous for calling you a devil.
