Advice needed

So I decided to give my baby daddy another chance. He had some shit going on with the girl from work. He told me they weren’t that way anymore. So we was talking on the phone, he had his ear bud in and she was nearby so I told him I wanted to hear how they interact with each other. He did as I asked and it was like really quiet for a minute and next thing you know this girl straight up ran up to him grabbed the ear piece from his ear said hell no started talking shit to me so I hung up. He claims he didn’t give her permission but I do believe he told her my intentions what y’all think?
