After lurking on here a while, and re-reading most of the advice and support given on the original thread to my situation last year, I've decided to 'come out' and update all those MNers who invested their time, and gave wise words of advice which I wasn't ready to accept and didn't have enough of a rational viewpoint to value at the time.
DH did decide at the time to stay with me and end the affair. But we just carried on with the hysterical bonding, and carried on with the frantic work / family life without addressing the underlying issues within our marriage, and as someone previously said while I was busy trying to repair the relationship, I ignored the fact that I couldn't repair the man.
It's not a suprise then, that the affair re-started earlier this year - that DH had not maintained distance from OW, and 5 weeks ago he walked out on me and the children following a final ultimatum from the OW.
They have already moved in together, and whilst it is early days on the emotional rollercoaster that I am now on, I am at least able to have some clarity and respite from the intensity of last year's situation.
I have now started counselling on my own, the children have been told he is working away at the moment whilst the initial dust settles, and he visits on the weekend, and is at least now spending quality time with them, and perhaps starting to realise the consequences of his reckless, selfish actions.
I don't know where things will go from here, but my priority is to gain strength and some self-respect to make the right decisions for myself and the children.
He is already expressing doubts as to his decision to leave, saying he will come to counselling, and that he is appalled and ashamed at his behaviour.
Whether this is guilt and self-pity or genuine remorse, remains to be seen in his future course of action.
I just feel ready to let those Mners who followed my thread last year know the outcome, and to acknowledge that in retrospect a great deal of sensible and wise advice was wasted on me at the time.
I hope that I will be a wiser, stronger person dealing with the situation this time around.
