This from Other Girl:

So, realistically, what's the maximum number of times you can fall truly, deeply in love? I think seven.... which would mean, I've used up all my turns so I should probably hope it's more like eight or nine. I don't really see how it could be though.

I, myself, would think it'd be alot less than seven but I hadn't really considered it as a finite occurence until a few minutes ago. I guess maybe seven is about right. I'm at six right now, not counting the kid...
