She is just probably happy to see your husband at weekends,very much like a young child she is playing you off against your husband.During the week your her best friend for company but come weekends it's go take a hike mom,dads home I don't have this problem with my greys,but i am experiencing the exact same thing with my macaw,my husband works away a lot,but is the best thing to her when he walks through the door !:unsure:
If she bites you then get your husband to put her back in her cage,she has to learn that this is not acceptable & she will see your partner is cross with her too,she may be reluctant to bite if she learns this is limiting her time with him
