>The Real Housewives of New York City's Jill Zarin, who's written Secrets of a Jewish Mother with mom Gloria Kamen and sis Lisa Wexler, shares tips:
DON'T LIVE TOGETHER BEFORE MARRIAGE
If he wants everything, he's got to pay for it. I don't mean like a prostitute-I mean put a ring on it.
VALUE FRIENDS-AND MAKE SURE THEY VALUE YOU
My breakup with (Housewives costar) Bethenny had to do with her not being there for me. Friendship's a two-way street.
BRING A SWEATER
I'm packing for a trip to Israel, and if it's a hundred degrees there, you know the air conditioner will be pumped in those restaurants, and I'm gonna die. We're cold people! We need a sweater.
