Man feels threatened by friend’s new girlfriend

DEAR ABBY: I’m a gay man who is best friends with “Carl,” a man who is straight. We are everything you’d expect of a normal friendship. On a surface level, there is no difference. He goes well out of his way to make me feel welcomed and accepted, and I appreciate it. Recently, Carl found a significant other. I’m happy for him, because he really does deserve it. The problem is, I am jealous. I know without a shadow of a doubt that my relationship with Carl will never be anything more than platonic. I think I know why this bothers me so much — Carl is nice, smart and attractive, and we get along amazingly — yet someone other than me is with him.
