<human>: It's a fairly new relationship. He's never cheated in the past, and gives me no reason to believe he would. The worst he does is like other girls photos on instagram- bugs me a little but that's so miniscule.

I guess it isn't much about us than it is about me. I was cheated on in my last serious relationship and it hurt me deep down inside my core. I have forgiven him, and we are on good terms. I never talk to him. 

Now I believe any guy will cheat on me. I get very jealous but then I'll reason with myself rationally and calm down. I'm protective. But I never fully voice my emotions in fear of looking controlling. 

Do you have any advice? How can I move on from these things?

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: I'm jealous and believe that my boyfriend will cheat on me without a second thought, even though he's been faithful. I'm crazy.
