Can you catch chlamydia from a blowjob

sweetone • Heartless bitch... i lied im a fucking cry baby

My ex claims he only got head from this random girl at a party & he ended up getting chlamydia. I didn’t fully believe him so a week later when he was telling me his symptoms I said to him ‘next time use a condom’- to try and catch him out. But he said ‘I never had sex with anyone I just got head’. Sooo- How likely is it to catch chlamydia from a blowjob? Is it even possible? Or is he just filling my head with even more lies. I mean he really has no reason to lie because I’ve already dumped him and made it obvious that im talking to someone new. But I just wanna know..
