My best friend of 15 years recently moved in with his gf. I am so proud of them and happy however she had a cat and 2 dogs. I go over often because he invites me to hang and it’s not so bad. But it’s a tiny apartment for 2 animals and 3 people. Now with him getting a 2nd cat it’s gonna be to much for my allergies to handle. It’s there place obviously and they can do whatever they want but it just sucks I won’t be able to stay the night or really even hang out there anymore. How do I break the news to him that I won’t be able to come over anymore (after they get the cat) not gonna shit in there experience. But I just know the day is gonna come where they question why I won’t go over
