I wouldn't bother trying to save your marriage.
It's not worth saving.
Your standards are sub ground level OP.
He plays games until dinner?
You are delusional if you think this waster is a good father.
He cares for no one but himself.
He certainly doesn't care for you or your children.
You need to return to work full time and to look at getting rid of your REAL EXCESS WEIGHT.....HIM.
He is the very definition of a shit husband and a shit father.
What a pity you let a few stone in weight becthe reason you thought you had to tolerate this.
He's no prize.
He's a waste of space.
I wouldn't tolerate such a lazy excuse around my children.
What an awful example of fatherhood he is.
In short, you deserve better.
Stop doing ANYTHING for him.
Feed the children and tell him he has to feed himself.
No laundry.
Do nothing that benefits him.
Tell family and friends the truth.
Get your paperwork together.
Do your figures.
Sort your job out.
Your marriage isn't worth saving.
You have given this waster 10 years.
Don't give him any more time.
Someone so selfish can't change.
The childminder story is so embarrassing.
If you can organise counselling I really think you should.
The fact that loosing weight has finally triggered you is so sad.
You always deserved the load being shared.
