WD mate,
I could name 10 people who i know who in the last 3 weeks have split from their long term partners and i reckon 9 out of 10 must be back together now, some strange stuff going on, must be the weather or thehour going forward of summat!
There is something in that theory. Most break up's happen in February/March (something to do with getting Christmas/new year over with). My hubby and I (before we were married) split around this time a couple of years ago for a few months.
