I need to check the recent call logs of a mobile number online

Oh my god, @glory0! Is it… is it really like that? Can they… can they really find out? I can’t… I can’t let him know I’m onto him. He’s… he’s been so distant. I need to know! But what if he finds out I’m tracking his messages? Or… or a keylogger? Is that even a thing? Something discreet, you know? Something to see who he’s texting, what he’s typing… please, just tell me if there’s anything.
