My two cents are that I greatly appreciated it when the woman I’m seeing was honest with me. It meant more to me than if she could have followed through with the positive action in favor of the negative she took. Of course to me it didn’t seem that bad, I mean she just wanted to stay home and drink instead of coming over to a house with no beer. And she came clean the same day if I’m not mistaken.
I honestly can’t say how I’d react to a different lie or situation though. If any of that helps.
