Opinions please.

Please tell me I’m not exaggerating. So I was helping my boyfriend apply at jobs. Well while my phone was updating I decided to use his phone, continue trying and applying for him. As I unlocked his phone I noticed Snapchat was opened. He had UNBLOCKED & SEARCHED his EX not to mention he searched her up twice because the first account was not hers. I specifically told him to block her because we’ve had problems previously with that girl. In 2019 he had added her and was messaging her behind my back ON HIS OLD SC ACCOUNT. When I found out and confronted him and he immediately blocked her. I know that should’ve been more then enough. But I thought maybe we can get past it. 2 years later and with our 3 month baby girl , I see this. What do you girls think?
