Despite having fucking other girls at the same time, she was my favourite, and now after being told that she’s found a guy she wants to be exclusive with I can’t help but feel betrayed and deeply saddened.

I’ve obviously developed oneitis and I can tell that this is just my ego talking, but I just can’t shake this mental and emotional pain. I’m having trouble sleeping and functioning correctly, and my drive to pick up and seduce new women has completely dissipated.

How can I shake myself free of this pain and move on to being happy and content again as soon as possible?
