Yeah, OK.
I'll show this post to my wife later and tell you what she says about my cutting the leash... if it can be printed in a public forum.
And before anyone tells me how whipped I am (something I do joke about myself), I would not allow her to just disappear alone for an undetermined amount of time either. Knowing where she is going and when she's expected back is a given.
I have disappeared myself for up to 48 hours when I was younger and single. Anything more than that seems pretty excessive to me.
