The French Kiss is a good movie to watch if you feel the one you love is not acting like he loves or appreciates you.  The Frenchman, Kevin Klien, tells Kate, Meg Ryan, how to WIN her fiance back.  His lessons make sense.  Don't beg, or try too hard, but keep a level head and find your happiness.  Find out what lights you up...don't sit pining for what brings you down.  

There is a quote from the movie that keeps popping up in my mind.  Her finance asks her why she looks different, more sparkly. She responds, "Why weren't you the one, Charlie? The one who turned on this big shiny Kate-light that burns so bright?"

I recommend watching this movie...it's light.   And when you see how she is left open and bereft and outraged, you can see how she gets herself out of it....   Not a panacea, just a little mind-set tweaking.
