It’s very rare that one person is completely oblivious to when the other is having issues in the relationship. And since you’re here, you’re probably under the impression your man might be thinking about leaving you.
But think about your own happiness. How do you feel about the relationship? If you’re not having fun anymore, your man has noticed. They might not be able to pick up on as many things as girls, but they can at least tell that much. And if they know, they might be feeling insecure about things, too.
