Every time I call the guy I'm talking to, I get a phone call from his ex the next day

She is likely going through his phone every time she sees him. And he's too dumb to delete your number or to figure out that deleting your number only puts your number in a trash or recycle bin, where it can be restored.

Or she might have downloaded an app to track his phone calls. Or she knows his phone password account and she just regularly goes on line to check to see who he calls.

But this is all beside the point. Red flag. Get away. Now!

oh boy.. she is completely derranged.  I know cause I did this.  She is logging into his cell account online and seeing the phone numbers he is calling and texting.  You most certainly bring it up and tell him to fix it or audios...
