love IN or love AND aoe?

[AlphaPhiBubbles]

So, obviously without revealing anything about what aoe means or is....what is the correct way of using it at the end of a greeting/letter? At first I always said Love and aoe, Nicolle" but then I heard the proper way to use it was "Love in aoe". So ever since then I used the latter...but then I was thinking about it, and I think the first one makes more sense. So which is it??
