You need to slow down with him. Right now is breeding season for these guys which doesn't help you. It looks like he has chosen your husband as his human. Try only being the person who brings him treats. If you can increase your value to him, it will increase his trust of you. It's difficult for you but if you are patient your patience will pay off. For my girl to accept my husband and son took her almost a year.
