Trust issues with husband's phone

So I'm well aware of how this is a ME issue. I have had too many exes cheat and hide shit on their phone including my now husband. So its an insecurity I am constantly working on within myself. My husband can be a bit too friendly imo, like tells women they look good or whatever. Which is fine. It should be OK for a man to compliment a woman w/o sounding like a creep. But evey time I randomly go through his phone which isn't a lot at all. Maybe like 3 times in a year if I had to say a time, I find shit I don't agree with. Like him telling a woman he really liked her shirt in the last pic she posted in a PM and then after she says it was actually a bra he says that she was rocking it and that he wasn't complaining. Idk typing this put I feel crazy but it's like every single time I see an inappropriate message to a girl I don't know. In the past he was talking to his ex about their sex life and how great it was and ever since I have been insecure.
