Believe me, he will hurt Comet and you too! He is a mean nasty person.
I am a dog breeder, and I always had dogs even when my husband was drinking. He never hurt the dogs or me for that matter, but did say mean and spiteful things. He would pick on my foundation dog, the dog that started my kennel, with words, but he never ever touched her.
Don't you see, anything that means anything to you, anything that is special to you is on his list to hurt or get rid of? Don't you see that? It's the best thing he can do without physically hurting you but hurting you just the same.
Sometimes the mental abuse is worse than actual physical abuse. At least with physical abuse, as much as I abhore it and have no respect for people who inflict physical pain on others, you have something to show for it, be it a bruise or whatever. With mental abuse there are no visible wounds. It's sad.
