I am in the same situation as you. Wife is having a midlife crisis and my 3 year old son is: 1. Regressing, pretending he is a baby when mommy and daddy were together. 2. Peeing in his pants like a baby even at night in bed, he was fully potty trained before separation. 3. He started kicking me, biting me and spanking me occasionally, he never did that before. 4. He wakes up at night saying "mommy......mommy.....".
It breaks my heart, and this is what has been helping so far.
1. I keep telling him that mommy is a good person and I that I will always love her, it calms him down and he can sleep better. 2. I keep telling that mommy might come back someday and that we just have to be patient and wait, again, it calms him down and makes him happy. 3. I keep telling him that mommy needs to be alone without daddy for a few years, it calms him down. 4. I keep telling him that I love him and that I will always be there for him. It calms him down and makes him happy.
