Am I wrong?

I just feel like my boyfriend of three years is so perfect and flawless, that something have to be wrong with him. 
Because of this worry, I have gone through his phone several times, only to fine nothing.
Everything has always been perfect between us. He treats me like a queen, we never argue, and he wants to marry me.
Am I a psych for wanting to find something where it seems that there's not? When he gets a text, I have even found myself wishing for it to be a girl so I can reveal the "truth" about him 😩
I just have this odd feeling that tells me that nothing is perfect and something gotta be off.
