You can’t hold a marriage together on your own, he needs to be willing too
It’s time to support yourself, be nice to him if you can ( so it’s not akward with the kids / though I would visualise kicking him where it hurts every now and then to vent my hurt and frustration )
Make sure he takes on half the responsibilities of the kids at least ( no slacking set the precedent )
Discuss a time scale for the trial separation .... so he doesn’t leave you hanging forever ... saying that try to move forward like it’s forever as much as possible
On the nights he has kids get your friends in ... you will need company rota them in.
Bottle of wine and nibbles ( you provide nibbles friend brings wine to share )
Movie out a different night
Clean and clear out the house like you have meant to
Cry
Join a gym or go swimming
Keep busy do every day tasks as well as new social activities keep moving at some point you will stop doing the motions and you will be living your life again
It’s hard when your the one left behind he may discover the grass isn’t greener , but don’t wait for him ... he forfeits that right by walking away x x
If he changes his mind it’s on your terms if he doesn’t ... you haven’t wasted time x x
You are worth loving don’t doubt that x
