<human>: Give me the gist of the text in a nutshell

My boyfriend has never done anything to break my trust. My self esteem has never been high, but plummeted when something happened a year into dating my bf (not having to do with my bf). My bf knows that I've been struggling with my confidence and has been trying to give me as much verbal affirmation to show me he loves me, but I've become anxiety ridden and always got jealous.

90% of our fights were because I got jealous. Obviously my bf has been worn down and has begged me to please trust him. I tell him that I do trust him, but I'm just worried he'll find a girl thats more attractive (personality and appearance wise). Of course it still drives him crazy.

I have improved a lot and have been trying to be more understanding and open minded, but he can't trust that I trust him. He says that I have to show him that I trust him in order for him to be able to be comfortable talking to me about anything that involves a girl. 

The problem is I'm really trying and I wish that he'd open up and share things, but since he thinks I'll flip out, he hides the most trivial things... And I understand it but the feeling that he's hiding something brings back my anxiety, this making me make him nervous again.

How can we break this horrid cycle?
