Welcome to the forum! Definitely check out what Noodles sent. Can definitely attest to the unpleasantness that is a conure bite. My GCC is being a hormonal little boy and is deciding I'm sometimes a good chew toy. The important thing is to not react, put the bird back in their cage, etc. When Calum bites me, he gets shunned. For a bird that constantly wants my attention, this is very upsetting to him and bites are few and long in between. It HURTS to get bitten, trust me.
As Noodles said, who the bird bonds is completely up to the bird. Please don't be offended by the conure choosing your husband. The bird may eventually warm up to you and share his or her affection with you. My grandma didn't want it, but my GCC has also chosen to be affectionate to her. Until about a year ago, Callum didn't care too much for my grandmother. Now he headbobs at her and loves to groom her hair and ears (which she is not fond of and Callum just can't understand why). My late budgie, Burd, decided my grandpa was a perfect companion for him. This bird would fly around the house, looking for him, and then land on his head on or on temples part of his glasses. My grandpa thought it was cute how this tiny blue budgie chose him.
Check out those links and take it slow. Two weeks might be going too fast for the new bird. If anything, have your husband attempt the training, the bird may respond better. Then, after a while, you and your husband start training the bird together. Then, you can be the one who gives out the treats. If anything, have a pocketfull of treats and give the conure some every time you're near him, only if he's doing his best behavior. A way to an animal's heart is often paved with yummy treats!
