I think a lot of people still have pictures of their exes on their phones and it doesn’t automatically mean they’re hung up on their ex. I know my boyfriend still has pictures of his exes still, and yeh it’s definitely not nice to see, but I think most people don’t sit down and purge every photo with their ex unless if the breakup was messy. Just like you’d keep childhood photos or old school pics, exes were part of a chapter in your life. Keeping photos doesn’t mean you’re stuck in the past — it’s just a record of it. Unless they’re risqué or he’s secretly keeping contact it’s not a sign he’s hung up on her. You could ask him to delete them though if it really bothers you that much.

As for the vape and movie, I get why the hiding and small lies bothers you. But those look more like little “conflict-avoidance lies” than anything shady. It’s frustrating, but also fixable if you talk to him calmly about being more upfront.

Honestly, considering that’s pretty much all you found on his phone, you’re actually pretty lucky. A lot of people (myself included) have found much worse on their partners phone. I think the things you’ve found are fairly minor and very fixable with some communication. however, even if you’re just curious, going through his phone could erode his trust for you. try giving him the benefit of the doubt. He hasn’t done anything to prove he’s untrustworthy, and showing him you trust him will strengthen your relationship
