Help!!!!

My boyfriends so-called ‘crazy’ bm has sent me texts of them continuing a relationship behind my back while I was pregnant last year. He claims she fabricated and made up the texts which I don’t believe at all. She sent a video going from the text chain to the contact info and showing his number. He sent me this screenshot along with a message telling him that she’s going to purposefully ruin my Mother’s Day to break us up, and pointed out the fact that his number is in the contact, but the +000000000 means that it’s fake.. can somebody tell me what the zero’s circled in red mean before I flip my shit? No smart remarks please. We just found out I’m pregnant again earlier this month and I really thought we were moving in the right direction. So I hope you understand a part of me is desperate in hoping it was really fake despite my gut feeling❤️ thnx

* google says that people use that technique of the zeros when scamming and fishing, but in the video she sent me going from the text chain to his contact info, his phone number is in the place where the zeros are, along with time stamps and everything. I’m just heartbroken trying to convince myself it isn’t real😢
