He is an addict. He will lie to you, hurt you, continue to steal and pawn until there is nothing left. Then he will steal from you, your kids, anything he can. Addiction is progressive & if you continue to stay in it he will mow you down.
When the pain of staying with him outweighs the pain of leaving him you will make your choice. Noone can make that decision except you.
I feel your pain, I have lived it. Please protect yourself and your children.
Hugs,
Teggie
