This Andy fella sounds dangerous to me. If he'll abuse one of your dogs then you aren't safe around him either. Do the dogs belong to you? Do you have a friend or family member you can move in with for awhile? Where you live, is it your place or his? If it's yours, kick his a** out and take out a restraining order on him. It sounds to me like he's playing mind games with you and is manipulating you which is, in itself, very dangerous.
Best of luck to you, Tonya, and may God give you the strength to do what is right for you and your babies.
