what do I do? chlymidia!!!!!!

ANSWERS PLEASE! So a few months ago I had sex with this stupid mother fucker who is now in the military. He doesn't have his phone because it's training and won't be back for 3 months. I figured out I have chlymida from him. How do I tell him? And would it be wrong not to tell him?? I kinda don't want to because I fucking hate him. I was drunk when he had sex with me and started crying saying no, and his best friend came in yelling at him to "get the fuck off and get the fuck out"
