Question: I've been dating the same guy exclusively since high school. I'm now 26, and we've been talking about marriage. I'm crazy about him, but I worry that I will regret limiting my dating experience to just one man. Should I explore other options? Her Take: If you've been with your boyfriend that long and are still "crazy about him," that's pretty promising. But you're smart to ask these questions. I think you could have regrets -- dating around often shows you just how many wrong men are out there, which makes the right one feel that much righter.
