So yeah this is quite toxic I (M20) believe to be thinking like this but the thought of a girl who I am crushing on being with another man is bordeline repulsive. For me it feels like that I’m already in a relationship with them and if they are with another person (cheating) then that will induce the same feeling I’m experiencing right now. What is making this a bit more toxic is that I want to be trying out dating more while I am casually seeing someone
