I think it depends, whether you are just b/f, g/f or husband/wife or just friends or family member or so. Just try to think what you did wrong and what the other person did wrong. Do you think you can patch your mistake or the other person can do it.

If not then talk frankly and just be out or as Mr Hyde said run away ! Anyways, hope your relation with whomever it is will smoothen.
