Hi, my husband is also allergic to all animals basically. And the animals that he's not allergic to, it's their food that irritates him... We cannot have any kind of pet in the house
To tell you the truth, I was also nervous because I really wanted to get a dog, but now I've made peace with this and don't stress about it. We just won't have a pet and that's it. I'm trying to focus more on the positive side of not having a pet so I don't feel bad about it.
I think that you too will get over this at one point. You should just give it time and not focus on how sad it makes you. Think about your amazing husband and that he'll feel better if there's no pet in the house that makes him anxious or nervous.
I hope you find a solution.
