Relationship issues

Okay so my relationship overall has been great. My boyfriend is an amazing man and is as respectful as anyone can be. Lately though, we've had a couple of small issues. One being that he still has pictures of him kissing his ex on instagram and the other day when I was picking a playlist on his phone for us to listen to I saw a playlist that was set to private that was titled his ex girlfriend's name. Other than that we've had a disagreement on whether porn belongs in a monogamous relationship (ik that subject has sparked controversy on here so let me just say this post isn't about the morals of porn and I don't think one standard can be applied to all relationships) that being said the issue is that he wasn't honest with me about it. We both place a lot of weight on trust and honesty in this relationship so it stung. I've talked to him about the first issue and he said he'd change it bud it's been weeks. And I'm currently texting him about the second issue of honesty. Have you guys had similar issues? If so how did get through them. It's these little things that make me feel like I'm not respected.
