Ounce,

Bluebear described it well.  Like everyone I've had to process "the switch", "the light switch"...the withdrawing all emotion, affection and love for me..also known as "the discard" or rejecting us.

It's not something that we could do to someone we loved.  Yes they weren't true to who they were..but we could not be like that either.  Its a foreign moral behavior to us..and cuts and hurts like a getting hit by a bus.

Do whatever you need to do.  If it works for now to have him there as a roommate for financial help and with your kids then do that...for now.

Do not beat yourself up..you have him for that.   Build your support system and know that you loved fiercely and loyally.

This is not us leaving them..this is them rejecting us.

A kind ehug.
