Whitney Houston was a legend, and there's no question that her tumultuous relationship with Bobby Brown led her down a pretty bad path.  Here's what you can learn from their mistakes:

1. Just because you love each other, it doesn't mean you're right for each other.  Whitney and Bobby had a rocky relationship. You can be in love with someone, but it doesn't mean they're the right person for you. Think about all the abused women out there who love their husbands.  Should they stay together?  Probably not.  Bobby Brown was a horrible influence on Whitney, and her family hated him for that.

2. Don't be pressured to do anything you don't want to do.  This one's pretty clear. And also, don't do drugs. Ever. Because the crack is wack.

3. You have to set a good example for your kids.  Whitney and Bobby's daughter, Bobbi Kristina, has also allegedly had her own problems with drugs.  She was photographed snorting cocaine, and she also apparently got high after Whitney's funeral.  Your kids look up to you, and they often emulate what you do.  Remember that.

4. Don't put aside the things you love for your significant other.  Whitney was a brilliant singer.  During her time with Bobby Brown she lost her way and stopped singing, when she should have been in her prime.  Please don't put what you love on the backburner for someone else.

5. And finally, don't ever, ever let anyone film a reality show about your family. Nothing good can ever come of it… it's how the world was introduced to Kim Kardashian. If that doesn't horrify you, I don't know what else will.
