What to do

Londie
I told my boyfriend can I borrow your phone and his answer was no !!! I was like why ? He just screams No !!! And drop it I was like wtf I just wanted to get the pic that we took together . I just didn't want to fight so I just let it go .. I wanted to see his phone so bad what his hiding why he doesn't let me see his phone ... luckily he left his phone unlock when he went to the restroom I got his phone and went to his pics I don't know why but I did and what I see was just porn videos all his memorie was full of porn videos . He told me he didn't watch porn videos I was like wtf I wanted to search more but he got out of the restroom.. idk why but I have a feeling his hiding more stuff from me .. I told him again Can I check your phone and he said No like I don't check your phone u can't check my phone I was like I don't have anything to hide here my phone check then he gets mad ... idk how to deal with this what should I do what to say ... or i am over reacting and it's nothing ..
