Oh heck no!!!😡😡

So me and my boyfriend was talking/arguing about how he always hide his phone when he text, now I'm working on my trust issues not saying I don't trust him but I been through man. So while he is trying to pull a text to prove some point I snatched the phone but didn't go through it, low and behold his phone starts ringing with the caller ID saying "ANGELA BLUE CLUB NASTY" like wtf. He answers because I told him to of course and tells the girl tell me she is nobody to him. I listen as she tells me it's nothing not even a history of anything she apologizes and all that and promise me that, that will be the last I hear of her. I respected that but told her to make sure she never use this number again. Ugh. I wonder who else just checks in randomly and if he will tell me smh.
