The funny thing is.. when I brought Chloe home I was actually getting upset if anyone else wanted to feed Chloe or do anything for her first before I do it. I wanted Chloe to attach to me as her primary caregiver, lol.
Don't worry that Jasper cuddles up to your hubby, I'm sure he is attached to you just as much as you are to him.

Are you home more often than your hubby? It could be that he see's your hubby less often than you so at night he just wants to cuddle to your hubby. I'm the one who spends the most time with Chloe, so when someone else comes in the house - it's forget about mommy time!!! Sometimes she'll even pee from excitement! But after she calms down she's like my shadow, lol. She walks around after me and when I put my makeup on near the dresser she always lays down next to me and watches.
You haven't lost Jasper to your husband at all so don't worry!

Yorkies just get moody.. but they always remember who mommy is,
