The other woman

Before we met, Clive worked/lived/travelled in the USA and Canada. 

Yesterday, my S-in-L brought a box of letters and cards Clive sent to family during that time. Items saved by my M-in-L.  

I had a flick through them and read one letter all about my predecessor. It made strange reading and Clive was clearly smitten.  Had things turned out differently, he may have stayed in Philadelphia and we never would have met.
