It's often the advice here, whether it's about too much golf, possible or suspected infidelity, too many boozy nights out etc.
But is it actually possible to control another's behaviour like that and maintain a proper relationship? If he needs managing like that to behave in a way that's acceptable to you, is the realtionship worth the effort? I.e if he won't do it just becuase he wants to treat you well, what's the point?
Anyway have you ever had to "nip it in the bud" and gone on to have a successful realtionship?
