somebody help me

i don't know what to do. i can't do this shit anymore. today he literally stripped in front of me. yes, ok it was in the changing room at our gym but how the fuck is he expecting me to sit there chilling when he's acting like he's on magic mike??? how did i react? excellent question. i yelled so suddenly and so loudly that apparently i dislodged smth in my throat, then ran away like a little bitch. i think he thinks i had a seizure. I DON'T KNOW WHAT TO DO.
