My boyfriends a fuxking liar

So a couple of weeks ago, I saw my boyfriend unblocked a couple of his exs numbers (idc what you think, they are exs for a reason he doesn’t need their numbers) so I just asked my boyfriend why he unblocked them and he swore UP AND DOWN he didn’t unblock them...(okay so sketchy already cuz numbers don’t unblock themselves) and then today I was going through his photos on his phone to find a good one of me and him for a new profile pic (genuinely) and saw a screenshot from 11 days ago from one of his ex’s that talking about something from work. I never heard a word of this & I’m fucking pissed. I don’t wanna fight with him or make him mad by bringing this us but do I have a right to be upset?! How do I confront him?

Update - I confronted him. He put it on my life it wasn’t his ex and made up huge lies over and over again and lied to my face.... so I ended it. I’m 8 weeks pregnant & it’s going to be so hard, but I deserve better...
