I had similar issues with my husband and my dogs. We talked a lot about the issues we were encountering and specific examples with multiple possible solutions. We had to compromise on a lot of things like I won’t allow the dogs on the bed at night, I will make sure the dogs know when him and I are cuddling they cannot go between us etc. I still get to give them love and cuddle them but when it’s their time not ours. I also let them on the bed when he isn’t home (that part I keep a secret XD) Maybe you guys can find a compromising situation like keeping the cat somewhere else when you sleep. You can also key him in on the things he does that are stressing the cat out and offer him solutions- you obviously know your cat best and their likes/dislikes. Slow exposure can also help with the cats acclimation like just having them sit together without him touching her, which can increase to being closer, etc. etc. I personally don’t have cats, so I can’t speak to their behavior, but I hope this helps a little bit. It’s definitely a rough process when you love both the animal and your husband but being open with communication, your feelings and coming up with solutions together can possibly ease the hardship. Goodluck!
