Are these the same dogs that he brought in & forced on you because you weren’t ready to love another dog??? Since he bought them, adopted them, or whatever, they are his dogs & it’s up to him as to whether to keep them or not. WHY did he call you to tell you to call your Mom to say goodbye to them when he could have just as easily called her himself??? Sounds to me like he wanted to upset YOU!!! In the eyes of the law, this is a domestic dispute aka family problem & they won’t do anything to get in the middle of it.
It sounds to me like it’s time to take Phoenix & move out where you have more control of your own life!!!
