7 questions successful couples should be able to answer

People in healthy relationships know they'll always be learning about their partner - and their partner will always be surprising them.

But there are certain things about your partner and the relationship in general that you should know pretty early on. We asked a bunch of experts - including a dating coach and a marriage therapist - to tell us the key questions that couples in successful partnerships can answer readily.

Note: If you can't answer most of these (admittedly tough) questions, that doesn't necessarily mean you're headed for a breakup. But it might mean you and your partner need to have some real talk, so that you both understand what you want and expect from the relationship.
