When DH and I moved in together I had to give away my 13 yr old big fur puddle of a cat, Spot. THe new apartment didn't take pets and DH winces with disgust when touched by an animal. It was one of the hardest decisions I ever had to make.
DH never asked me to get rid of Spot and made it clear he would be willing to move and take the cat back when the lease was up, but he also pointed out that the horrible wheezing I did, and the gagging choking non-relievable cough, might be from a cat allergy. I poo pooed this because I had always had cats, and, well, it had honestly never occured to me (duh).
I got rid of the cat, and my lifelong cough, choking at night, wheezing, and gasping went away as soon as all the cat hair and dander was finally gone.
I am so glad now that DH's dislike of animals (I adore pets) wasn't a deal breaker. I go to Mom's to visit, and I take both an allergy shot and a pill to deal with the cats and dogs, and in an hour or 2 I'm starting to wheeze anyway. I honestly feel so much better now, I can't imagine how I lived in houses with animals my whole life. I still love my fat cat, just from a distance!
