Would you stay or leave

My boyfriend didn’t even know that he had chlamydia before he started dating me(dating almost two months) I got tested in my pregnancy for them because they do it I guess all cane back negative & he blamed me for it saying I’ve been cheating on him which I haven’t. Well, I’m just wondering would you stay with someone still even if they knew they didn’t have it? By the way they only tested for it because of the birth control I got on.
