Oh pet, i feel so sorry for you.
This is so hard and so lonely.
I really can't imagine. At all.
The fact that he has left is good.
Your children are upset because the know well, that yours is NOT a happy home.
Please don't lie to them.
Even though that may be very hard because you really want to protect them.
Much, much better to say that ....."mum and dad are having a very hard time. Adult relationships are complicated and can be very very difficult to understand for children.
We both really love you.
However, mum is going to work really hard to do what is best for you and her."
Only a suggestion.
Others on her are truly fantastic for advice.
Hopefully they will adise soon.
You are NOT alone OP.
People you don't know are thinking of you.
YOU have done the right thing.
This could not have gone on.
I thi k it is sadly very telling that he knows very bloody well how badly he has treated you.
That tells me, clearly, that he knew bloody well how badly he was behaving.
How poorly he was treating you.
Thats so sad.
I can only imagine how sad you must feel to know he has had a super fast Eureka moment.
That would just piss me off more.
Deep breath.
Take your time.
See how you feel.
Please speak a little to your children in an age appropriate way.
Lying is just more confusing.
Better I believe to be calm, and positive that mum and dad love them, but that Daddy needs to stay with Granny for a bit.
Happy to be corrected by others.
