tested positive for chlamydia feel like a horrible person

This is not to shame anyone for anything sexual related this is just how the results make me feel personally.

I slept with this guy 3 weeks ago and we didn’t use a condom. I normally use condoms with every partner I have but this time I didn’t because I didn’t have the right size for him.

3 weeks later I got routinely sti checked. Just today I got my results and tested positive for chlamydia. I told him but he told me that it wasn’t from him. Even though it 100% is since I get checked after every new partner. I just feel like an absolute idiot. I know proper safe sex methods and didn’t use them. I just feel terrible now that he may tell all of his friends since we all go to the same college and I know all of them. I know chlamydia goes away and is 100% curable. I got my antibiotics today but he’s just denying it’s from him. I don’t know what to do I just feel so ashamed and I know he’s properly going to slut shame me to his friends and everyone we know in common. I just need support or advice, thank you♥️
