extreme seperation anxiety behavior from our rescue husky/malamute

We have had Roxy since last Oct. At first everything was fine, than on about my fourth trip with her staying at home with my husband it completely changed. Her separation anxiety was so bad she got extremely ill. Since it was winter she could come with me and stay in the truck. Than when it got hot I took her to doggie daycare until the fence she went over sliced her leg. So than my husband would keep her and she had gotten down to 30 minutes before she would stop crying and running back and forth inside. He can’t take her outside without her being on a leash, because she runs down the road to find me. But today was the worse, he would recline in his chair and she got up in it with him. Than he would lay on the couch and the same thing. But than he sat on the floor and she went and played by the door, but if he tried to go sit in his chair she did it again. Will this ever end or be less stressful for both of them?
