It's stupid for anyone to date, support, and be in love with him now. ATRL shade aside, he simply has not learned a lesson or changed himself. He needs help. He needs anger management. He needs therapy. Being a supportive girlfriend does nothing but enable him right now. If she really wants to help, she'll get his ass in jail for a shock, then straight to serious therapy. His behaviour will just stay the same if he knows he'll never fall on his face.
And yeah, even if it was Rihanna, she'd also be stupid and enabling. I don't think I ever hid my disgust with her for getting back and supporting him so much.
In that sense I completely agree. I thought people had a problem with her being sad and manifesting her sadness on twitter.
