I'm over it

I've been in a relationship for 7 months now. Back in December, I got tested for any STDs. My test results were negative. I just recently went to the doctor & my results show I tested positive for Chlamydia. So I approach my boyfriend about it. I haven't slept with anyone but him for the past 7 months. Recently there's been issues between us, where people are actually coming to me telling me things about him & coworkers at his job. His reaction was way too calm ... he kept saying he doesn't understand & that it doesn't sound right to him . He even started crying , saying he would never cheat on me & he doesn't wanna lose me for something he didn't do . I didn't get Chlamydia from a ghost . 😭 I hate that I love him so much cause I feel like I shouldn't be with him now ... I don't believe him as much as I want to 😞
