I had an affair (much to my disbelief), we were both married and both had children. He was a work colleague, and still is. I got found out by my husband and finished it. It then started again (me and OM were very good friends) and before we knew it, it was back on full again. Again, got found out, this time I finished it for good and have not been back since. Had another baby with husband but he then decided he could not forgive me and left when she was 11 weeks old.
I still work with the OM (albeit on a different floor).
He is still married, although his children are now grown up (the affair was about 8 years ago).
When my husband left, I did go out with OM one night and he was more than willing to carry on as before, but I had lost everything over his and my behaviour and I was not going to put his wife through the anguish that I put my husband through.
From a selfish point of view, I really did not think my husband would be that 'bothered' (n my naivety).
When me and husband were trying to make a go of it, he told me that he felt no anger towards the OM because it was not the OM that had done this to him, it was me and I was his wife.
My husband (we now get on very well) always told me that he thought me and OM would end up together (he is 10 years older than me) but it was never going to be that sort of relationship.
The OM just provided something for me that was missing (not sure what) from my marriage but I didn't realise that actually my husband could give me everything I wanted if I had only communicated more.
I look back on the affair as the biggest mistake of my life (easy to say now, why couldn't I see that at the time) and I will pay for the price for the rest of my life for what I did to my husband and my children.
