Sorry to be almost nasty with this comment but I have been there got the t shirt etc
As my wise old Pa used to say
"do not look back it is not the direction you are heading in"
Not easy but once they clear out, says it all I am afraid to say and to be fair it does take some bottle for her, yes there are two sides to every dissagreement.
Whatever happens be decent and be a man
After being married for 13 years my ex upped and left ( I guess realy we just fell out of love with each othere), it WAS hard £80k and a divorce later I have moved on and much happier for it now, one day I may get the chance to thank her, but to this day I have never bad mouthed her, I would not wish her any harm. But alas she became a stranger who I no longer knew.
