Hello, I'd like to help you with your question.
If you are giving your boyfriend mixed signals about staying over your home, it could be either the disorders you have or it could be that because of the situation with the cat, you are caught between wanting him there and not having your cat be fearful.
It may help to look at the situation in a different way. Consider if you did
not have a cat, would you want your boyfriend over your home as often as he is? If so, then you know that your feelings are because of the distress your boyfriend causes your cat. But if you still feel the same, then it may be because of your concern for your cat or because of the diagnosis.
Also, consider how much personal space you feel you need in the relationship. Do you feel good when you are on your own or better when you are with your boyfriend? Some people need time on their own in order to recharge. And wanting time on your own in a relationship is healthy. While it is tempting to be together all the time, each person needs to be able to be an individual then a couple in the relationship. Being together too much can hurt a relationship because you will have nothing new to add
to the relationship and you cannot grow as a person if you are together all the time.
I hope this has helped you,
