This is a very difficult time.
Why are the nursery calling you?
2 year olds can be stubborn, why are they not able to deal with her.
I would STRONGLY recommend you do NOT tell your husband that you are not in love with him, unless it's before explaining you want to separate.
Do you want to separate?
Because if you don't want to DON'T say something like that.
It can NEVER be taken back and will wound him in a way that is unforgivable.
So tread with care.
It sounds like he is doing his best and working hard.
This IS a very difficult time.
Can you at least try and plan something nice for Saturday night when your daughter goes down.
Get some nice treats in, a bottle of something, pick out something nice to watch.
Honestly that is all any of can do now.
I have 4 children and its all about nice food, special dinners, me baking their favourite cakes, biscuits, whatever.
Life is very very small, but it will pass.
We are all a bit bored and fed up, but we just have to try and get through it.
You can't change things at the moment but you can think about where you want to be at the end of this.
Do you want to be married and together?
If you do.
Start thinking about what you can do to get to that place with a marriage intact.
Believe me, this is what a lot of people are aiming for.
To get through this experience with their marriage and family happy and intact.
