Am i wrong to be angry? (Lil long, sorry)

So my bf and i have been having a hard time lately because he has been being sneaky so ive been going thru his stuff. He has access to my phone whenever he wants i have nothing to hide.

The last time i found something was about 2 weeks ago, his internet history said he was on a texting app. I could not login to the app because i dont know what he uses for passwords.

So i confronted him, he told me he has no idea how that got there....sketchy!!!? So he just brushed it off and ive been mad.

Tonight, i go thru his phone while hes asleep and i check his Facebook messenger, hes talking to this girl and talking about sexual tension and her writing a erotic story about them.

IM NOT CRAZY RIGHT? IM ALLOWED TO BE MAD? ...Am i overreacting?

Then i check his Googlemaps, thinking maybe hes gone somewhere when im not around or something. -_- annnd his saved location for "home" was in Florida! WE LIVE IN NEW YORK!

i took a screen shot but i obviously cant post the address.

What do you think?
