I thought I'd give an update... and this may be surprising... I'm at a stage whereby I now quite like not being in a relationship. I am outgoing but like my own company.
WW hasn't yet filed for D although I know she had completed the forms many months ago. My legal advice is surprised she hasn't yet filled.
The kids and I have great times together. I'm now enjoying it more at times than when with WW. One of the kids wants to live with me. The other is under an awful lot of pressure from WW not to stay with me - WW is spending a fortune in legal costs to ensure the kids go to her. It will be months more before a legal decision is made over the kids and the odds are still stacked against me.
I keep going with honesty and integrity in the hope that justice will prevail.
