My Wife has walked away

[Intact]

So today my Wife packed a bag and left the family home. We have a 8 year old son and she wants 50% custody (I'm fine with this).

We only managed 2 counselling sessions and she just told me that she didn't love me anymore - in fact she told me she has no feelings for me...

I've read the book - it fits into the Walkaway Wife category perfectly...

I presume they don't often come back?

I did speak to her tonight and she told me "her mind had never been clear" is this a normal thing to say?

My Son is distraught and it is truly heart wrenching.

Any advice would be most welcome.

Thank you.
