I went through his phone 📱 😭🤦‍♀️

I was looking through my boyfriends phone and I seen text messages between him and his baby’s mom. I found out she’s pregnant and due next month. And he’s been having sex with her raw when he goes to her house to see their 1 year old. He’s over there 3 or 4 times a week . He sometimes ask her what she wants to eat . And I found out he got her chocolate covered strawberries as an early valentines day gift. I called her and let her know he has a girlfriend and she didn’t even know he had a girlfriend, she said they broke up 6 months ago . My boyfriend has been lying the whole time. We’ve only been together for a month and a half. I just feel so betrayed. Has this happened to anyone else? Can this type of issue be worked through ? He said he’ll stop and that he’ll start picking his baby up instead of going over there
