Hoosier, it is very early days for you yet. There is no time scale for how long it is before you feel able to catch your breath. One foot in front of the other is good. In time you will see things a little more clearly and start enjoying somethings.
Just be kind to yourself for now, spend time with daughter and do some fun things together. Don't worry about H you have no control over him.
One of the best bits of advice to me was fake it til you make it.
I didn't thik it was really helpful but did it anyway then one day I suddenly realised I hadn,t thought of H all day and was actually laughing at something, real laughter not pretend.
The letting go of the ideal of marriage is so hard, we wear rose coloured spectacles and often that was not reality.
If we can go back and honestly examine what our marriage was, it helps us to make changes that will initially help us and also help us if/when our H return.
Take care.
