I told my first wife exactly like this...
About a year building upto this moment, we basically led seperate lives, she worked shifts, didn't like my firends, and i knew this had no future, and there was no love on my side....
So she went on holiday with her mum abroad, i was invited, but kindly declined. I decided this would be an excellent opportunity to finally move out and make the spilt. So all my clothes, hifi, cd's, gear etc made a quick move elsewhere. Obviosuly i left the washing machine and the c/htg boiler.
The day arrived for me to pick them up from the airport, the drive home is pleasent, with us exchanging casual conversation. I drop the (ex)mother in law home. We finally arrive home, we get inside the house, and she puts two and two together and says "Whats going on?", i basically look her in the eye and say "I'm leaving you". I then left.
Then went to the local for a few stiff drinks with a some close friends who didn't believe me, but that is how it happened.
