Hmmm....if you've had him for just 1 1/2 month, he may still be adjusting to the surrounding environment. If he is bonding with your husband, seems that that's his favorite person. Birds, especially the larger ones, usually bond more closely with one member of the family. To get him used to you, you will need to spend more time with him. Play with him everyday, talk to him, and interact with him. Be the main person to feed him and show interest in his activities. He is very young right now and hasn't been with you for long, so hopefully, if you spend a lot of time with him on daily basis, he will get used to you and become your best friend. I have never had an African Grey, but I have two cockatiels, and it took them around 1 month to trust us completely when we brought them home, however, they were only 3 months old when we got them, so they're young age had them thinking we were their "mommies" so I think that's why they bonded with us faster. Good luck on your bird and keep us updated.
