<human>: We've been together 14 months, living together since the end of April 2012. This has only really been an issue for the past few weeks, perhaps a month.

My boyfriend is insecure. Extremely. It has recently been putting a serious strain on our relationship, as very small things set him off. 

A single word, look, anything from anybody that may *possibly* indicate they think he's wrong about something makes him furious and overly defensive. Even if he just mishears me, replies to a question or statement in a nonsensical way, and I say, "Oh, I think you misheard me, what I said was [X]," he loses it and says I am calling him stupid, "demeaning" him, etc.

It's bad enough that I'm fairly certain if I ever broached the subject, no matter in what context or how gently it may happen, that switch will flip and he will get upset, effectively halting the conversation and forcing nothing to happen.

He's had a great job right out of high school, is handsome and fit, intelligent, has always gotten a lot of attention from girls...there's no reason for him to feel insecure.

What can I do to approach it, and try to help him? Insecure males, I'm lookin' at you here.

Provide a brief overview of the text.
<bot>: Boyfriend wildly insecure, seems to be in denial about it, I need a hand broaching the subject to help him through this.
