SAUCY SECRETS: My situationship won't commit but whinges when I see other men. Then he did something VERY weird when I was on a date...

Dear Jana, My best friend recently confided in me that she's been having the best sex of her life with her new boyfriend, and now I'm weirdly jealous. And why do you think there are sex coordinators on Hollywood movie sets - because it's a full-time job making sex look, well, sexy sometimes. I've tried hinting, joking and even being blunt about how she deserves better, but she brushes me off with excuses like, 'He's going through a rough patch', or, 'He'll change.' How do I get her to wake up and see what everyone else sees, that she's carrying this man and it's only going to drag her down?
