Would best friends make a good couple?

Well, I don't know you or your best friend -- so I can't tell you whether you SHOULD or SHOULDN't, but normally there isn't anything wrong with it. You just have to look at the type of people you two are -- some best friends can still stay best friends after a break-up. Some can't -- some will never be the same after a break-up. When dating a best friend, that's the one thing you have to think about and the one thing you two should make clear before you start dating. But if you two like each other, I don't see anything wrong with it.
