<human>: I am trying not to get freak out about this but things just don't seem to add up and I can't help but think the worst. So yesterday I get a text from an unknown number and it is a snapchat screenshot of a dick. Straight away I recognize it as my boyfriend's dick as I've seen it enough times and he has sent me similar pictures. I had a million things going through my mind but of course I'm thinking he has been snapchatting dirty pics with someone. I immediately text back *who is this?* but I got no reply. 

When I next saw my boyfriend I showed him the picture and asked him what the fuck the picture was. He straight away just said it was just a picture he must have sent me. Then when I told him someone had sent it to me he looked at the picture closer and said it *obviously wasn't him and I needed to calm down*. I kind of believed him because I guess I wanted to and I probably did need to calm down. The rest of the night he was almost teasing me that I thought it was him and when I asked him why someone sent me it his explanation was that it was probably a wrong number. 

But this morning I looked at the picture again and I am sure it is him. It all seems so weird – why would someone send me this? Where did they get my number? I don't really know what to do. Is there any way to prove he has been sending pictures? I guess that is the thing about snapchat – you don't know what people have been sending. I have now convinced myself he has been cheating but maybe I am just thinking the worst. I don't know. I need advice.

Give me the gist of the text in a nutshell
<bot>: Someone anonymously sent me a dick pic of my boyfriend that he must have sent them. He denies it was him. Don't know what to believe.
