<human>: Briefly posted something yesterday, then deleted because the situation escalated quite a bit.

I go to school out of state, and was texting my dad yesterday morning (so I know I was in his most recent text conversations.) Out of the blue I get a text asking "hey babe, how is your day off?". He has NEVER called me or my mom babe, and my mom was at work so it was not intended for either of us..

I did not reply, he follows up asking about the weather where I am.. still no reply, then he proceeds to accidentally text me again. It was obviously intended to go to someone he has met online, it had to do with logging on to a cam website, and then followed up with some pretty graphic descriptive text. 

I was shocked. I did not reply, but I do have my read receipts on, so I know he saw them. He then proceeds to follow up with another text asking about school.. I have not replied to any of these. I am shocked and disgusted and so mad..

In previous years I've accidentally seen his browsing history, but it was never on a dating site or a cam site like this. My parents certainly don't have an intimate relationship. Whenever I am home I notice that my dad sleeps in our guest bedroom, but besides that they seem the same. I just don't know what to do or who to talk to (I have an older brother). I am very close with my mom so it is killing me knowing this.

Condense the text into a few key points
<bot>: Dad accidentally texted me, thinking I was (presumably) some girl from a cam website, I'm mad, please help
