Simon I can empathize with that. Just when your guard's down you get a bad day and it hits you hard. I don't get many these days but felt a bit low two days after the court hearing when I found out the ex had been lying about what was said in court, made me out the perputator and all that. Not that it is anyone else's business anyway.
Just to put things into perspective, about 3 months after she left me, my Dad died. Going through that experience on my own made me realise that I could overcome the separation from my family.
Then I met a wonderful lady and tried to start again. Ended it after 6 months. Just too much too soon. Pity because she really is special and was/is a great help. Got on fantastic with my kids & me with hers, maybe in time who knows but I don't feel ready to commit yet.
Bring on Friday morning and the French Alps 😀
