... if every time you went to check your email on your boyfriend's laptop, there was no browser history or recently viewed documents?
*you live with boyfriend and have for 2.5 years
*he has a history of lying about looking at... stuff...
.... just trying to validate that I was right is questioning why he chooses to do this and hide all his ongoings on his laptop... if I'm out of line, let me know.

i've been there done that with more than one boyfriend. you are correct in thinking something due to his reaction. i wouldn't care if my SO checked movie times, weather, my emails, my history, etc. bc i know there is nothing to hide. it should be that way in a trusting relationship. him having that reaction shows he does have something to hide. this happened with 2 exes of mine and it was stuff i discovered by accident. having trust issues destroys the relationship, and i know that finding out about the internet stuff only led to other stuff. good luck, i hope you work something out. but some guys (and women) just get so addicted to that stuff on the internet they lose things in the rest of their lives. it's a shame that something that can be so good and helpful also can be so destructive. 
Run away, and run away fast!!
