Got the full email later in the evening. Nothing in it I didn't already know, even though she felt she was informing me. Haven't replied as I will check a few things first.

I was asked what the reasons for her leaving were today. I said all I had been told is that she was done, done, done. Our past had caught up with us and that she was going to have an affair and possible relationship. I have heard from others that W has talked to that it was because we were having too many arguments, grew apart, loss of connection and distant, lack of trust towards her with this work colleague.

Too many arguments- I agree with. It does take 2 and I own my part and is part of my self improvement.
Grew apart- think that happens when there is involvment of a third person.
Loss of connection- again like above plus stress and exhaustion on both sides during a very busy and difficult period in our life.
Lack of trust- yes I did as her actions were not matching her words but also contributed by not working on myself, again part of my self improvement.

I know she has been trying with little success to gather info on me, especially through the kids. I have not asked her or anyone about her and what she is doing. I don't feel her new life is what she thought it would be but it is her decision. I have tried to be a light back but I think my light isn't as bright as it could be. I am really 'meh' at the moment as to if I want this back. Financially it would be better but that will get sorted in time, my kids are a big factor but it is refreshing to do what I want with them when I have them. It has been a huge weight lifted by living how I want to, I was one of the those that got to the point of just trying to do what she wanted and gave up me. I am enjoying rebuilding me and the better me that I will be.

Time will tell and I know this separation is relatively early (entering month 4, 6months from BD) if I continue to feel the same.

I just got a promotion at work, will take over the lead of our project in the next few weeks. My head is not running at full capacity yet but it was an offer I just couldn't turn down. A couple of big difference between W and me are that I will do what I say I will do and I will push myself to better myself. I was going to post to my FB friends about my work but will hold off a bit because of her email as she told me that with the amount of money I was asking for the mortgage contribution, it is unsustainable for her... There is a legal loophole here so I will have to bend slightly on this unfortunately but not by as much as she is probably going to try.
