Awww...I know your feeling, this is NOT an uncommon complaint about any bird breed.
I had the same thing happen with me. I decided I wanted to have a bird again, I picked, purchased and brought home a beautiful lutino cockatiel. I was told this bird was male, but within a few days I knew without a doubt, she's a female and frankly, she could care less about me, EVER!
When she met my husband, that was it! I envision her with long black eyelashes she can flutter at him every time she see's him.
Mind you, I take care of our birds, I feed them, water them, keep their cages and dishes cleaned I spend countless hours talking to them, playing with them and he walks in the room and Chiquita just melts for him.
We have two other birds now as well, a pied male tiel and a male yellow sided green cheek conure and they don't seem to have a favorite human...at least not yet. They treat us equally.
Instead of being upset by it, just let things roll and enjoy the often humorous antics of your birds preference.
How old is your bird?
