Dating? Here’s some advice on the Big C’s: commitment and cohabitation from the book “How to Survive Dating” (Hundreds of Heads Books, www.hundredsofheads.com, $12.95), straight from people who’ve done it:

“It’s ok to move in with someone when you know for sure you want to be with each other through the end of the leasing cycle. Theoretically. And if you’re spending all your time together anyway, paying rent on two apartments is a pretty big luxury if it’s just for the sake of maintaining the semiotics of independence.”

—Bette Crawford, Philadelphia, Pa.

“If I hadn’t been used to living with him, I would have left after we got married. But because we shared a place and our lives before we were married, I already knew that he’s just like his dad sometimes and says stupid-ass stuff and then feels bad five minutes later. Now I can let it go.”

—Anonymous, El Dorado, Kan.

“My message to anyone out there: Please make sure you are married or about to be married before you move in with someone. I made that mistake and I am paying for it big time.”

—B.J., Brooklyn, N.Y.

“Living together isn’t as hard as people think, unless you’re a control freak (or your roommate is). Don’t expect a slob to change just because you constantly nag about cleaning up. Don’t expect a meticulous cleaner to relax just because you explain that a certain amount of bacteria is natural.”

“A relationship can work only if two people want the same thing.”
