STUBBORN BOYFRIEND.

okay so i recently found out that I have chlamydia & gonahrea ... I started dating this guy. Take in mind I still didn’t know i was infected. So everything was good and we ended up having sex .. well my dr appt was the next day & that’s when I got the news I came clean with him and I told him . I’m getting treated , I want the same for him but he’s being stubborn and saying he doesn’t think he has it and it’s no big deal so he won’t go see a doctor ... advice??
