Senegal Parrot suddenly started biting

I have had my Senegal Parrot for just over a year now. We bought him/her when he was a baby. He/she and I were very close but the last few weeks he doesn't want me and bites me. He now wants my husband and is fine with my two children. For the past three months several family members have been living with us. Would this be causing stress or be angering my parrot? What can I do as he is biting sore and making me bleed? I miss our closeness, can I ever get it back? Help!!!
