Yesterday, I was on my boyfriends snap chat and I had seen he sent a snap to someone (couldn't tell if it was a man or woman yet). So I clicked on the snap name and it was obviously a woman. No biggie. That didn't upset me.. Until I clicked onto the snap thread and seen two half naked pictures of her from a couple days ago. (All she had on was a bra, showing her ass and partial vagina)

I kept COMPLETELY calm. I messaged her and said she better not ever try to contact my boyfriend again and blocked her. 

When I had shown him what I sent he tried to act like he didn't know who she was, and acted like he NEVER seen them.. Then got upset at ME. 

Saying " why are you going through my phone for" " I don't go through your shit why do you go through mine" 

He swears on our relationship that he didn't see the pictures.. But come on. He's on his phone all the time when we are home.

I told him if I ever see that shit on his phone again I'm leaving him. "Accident or I didn't see it" or not..  

I don't know what to think at this point but it's eating at me.
