Would it be wrong to ask boyfriend to let me see his phone and check it or I’m leaving the relationship?

He is a great guy in all other aspects, but He is doing some sketchy things when it comes to social media. Facebook, Snapchat, messenger etc. I can’t say 💯 that he is guilty of talking or entertaining other girls but something doesn’t feel right. One reason is because he was entertaining other girls when we first starting talking (2 months into relationship) He has a passcode on his phone and refuses to share that with me, even though my phone is wide open and I leave it around because I have nothing to hide. He only gets on his Snapchat when I’m not around. I just don’t want to be hurt again and I feel like something isn’t right because of his social media behaviors.

Let me clarify that I have proof of him previously talking to other girls and he still denied it, even with proof in front of him. He also deleted me from Snapchat. I don’t want to get hurt but I don’t want to lose him.
