Exactly that ! Three years down the line and ex is clearly miserable with OW and baby, plus he's suddenly fat, balder and looks dreadful.
Instead of letting me get on with my life, he every now and then throws a curved ball our way (me and the kids). He's now taking me back to court to lower maintenance and he STILL asks the kids if "the coast is clear" when he comes to pick them up (twice a year as he lives abroad).
It's SO BORING and stresses the kids out, making his time in the UK tense for all.
Why can't he just move the fuck on and enjoy the life he supposed left us for??!!!
