Being best friends with his friends
Your partner is going to have some friends you’re not crazy about. You’re going to have some friends he’s not crazy about. To expect one another to become best friends with all of your friends is unrealistic, and setting yourselves up for some major fights. All you can ask is that your partner is respectful of your friends. But if you get angry every time he doesn’t want to attend brunch with you and the friend you know he doesn’t like, you’re asking for trouble.
