Bf looking at his friends gf nude pics

Sorry in advance 4 bein so long

So me and my SO went out on Friday to celebrate vday. We ended up at a bar in which his friend was there and dudes gf. At the end of the night dudes gf was naggin my SO of not heating his truck for me. So today 2 days later my SO is still complaining about her andbhow she needs to worry about her life and bf. Because her bf shows my SO nude photos of her, very graphic ones. So my response was well u shouldn't be looking at them. Thinking he was gnna say to me..i dont wanna look at them when i have u..or sumptn of those lines..but his response was...why not I'm a guy..am i wrong to be upset...now i no you've seen her naked and we see them at the bar everytime were out. Then he turns it on me and says oh I'm sure u hot things in your phone etc..and picks up my phone and starts looking at it..i kept folding laundry I have nothing to hide but when i picked up his phone and said 2 can play this game he chased me down and said no ur not aloud to look at my phone..I'm just irritated with him now...i had him leave...
