Trust Issues

My boyfriend is my picture perfect dream man. We’ve been together for nearly two years and he was everything I have ever prayed for and more. Before him, I had been cheated on by my toxic ex multiple times and been oblivious to it the entire relationship; needless to say, I have some trust issues. My current bf was perfect (almost too perfect) until our relationship got rocky and he broke my trust by messaging another girl that had feelings for him; he didn’t tell me about it and i found out on my own. I was shocked and absolutely devastated. After breaking up for about a week I decided to give him another shot, only because I could tell he truly was remorseful by his following actions. Since then (6 months ago) he has done everything to try and make it up to me and be a better man. Blocking the girl without me asking, letting me know when he hangs out with or snaps another female friend, etc. Even tho I’ve gotten better about it, I really cannot shake my remaining trust issues. I want to have a clean slate so badly, but I don’t know what’s hindering it! I do have a bit of anxiety, but I drive myself crazy when I see that he’s followed a random girl or is liking pics of girl friends in bikinis; the old me would’ve ignored it and thought nothing of it, but the emotionally scarred me automatically links it back to him trying to get someone’s attention or have bad intentions. Every time I’ve talked to him about this he gets frustrated because he’s “done everything in his power to make it up to me and be a better man, a like on a pic means nothing”. I truly believe this man is the one; we’ve had literally no other issues besides this one. Am I being paranoid? How do I cope and move on? I’m tired of it clouding my mind constantly and holding me back from being happy in my relationship.
