23M4A emotional cucking humiliation

I’m looking for a particular cruel person to have a conversation about the idea of my girlfriend not only cheating on me behind my back, but also developing feelings for the man she is cheating on me with. She would never do this irl i’m sure, we have a strong relationship, although she doesn’t know I am posting here.

I want to focus on how humiliating it would be, she is not only cheating on me, but she is falling in love. She’s wistfully thinking about him every moment she can. He slowly takes more and more of her time, even when he isn’t here with us.

In reality this would break my heart, but for some reason I can not shake the thought of it. I want you to get in my head and tease me, humiliate me, convince me of this, my worst fear, coming true.

The thought of her laughing with him, spending nights at his place, being introduced to his friends as his girlfriend, the thought of her trying everything she can to get his attention. Do I ever meet this guy? Is he a friend? A stranger? Is he more attractive than me? I am looking for a cruel/evil person to taunt me about this. Use reddit chat.
