DrP, I am currently going through a separation/divorce. We have just applied for the Decree NISI, so I can see where you are coming from my friend.
It’s been an emotional couple of months but a torrid 2 years for me. (I was falsely accused of a few things in work which needed emotional support from the wife, which never occured)
The separation /divorce was her idea and she has never once shown any emotion towards me during the process. At times I think, could we make it work, but her behaviour at times has been really nasty and unpleasant. So I am 100% sure I will be better of apart.
Sometimes people can change, the soon to be ex has pointed out my character flaws on a daily basis, and I am determined to change with any future partner.
For yourself, take stock. If it has got to this point then maybe it would be best to separate but try to remain friends.
Anyway, I have a patio to finish….
