In reply to Ughhh.

The coming happened and her (your words) drug addicted boyfriend stood by her and she did nothing than sing his praises, suddenly she leaves him and comments that it not her responsibility to look after no one.
Then! She's not only in a relationship with Pete but she's engaged and they buy a 16 million dollar apartment together.... minute's later its over. But lets not forget Big Sean and one of her backing dancers after that.
Mac's addiction and Pete's bi polar are not an issue for her because this was all public knowledge before she got with of them so it amounts to choices be it good or bad, and she was with Sean whilst or just after he was with Naya.
This is something to do with her. She needs to work on herself.
