My boyfriend and I got into a fight last week?

[Breezy Chic!]

Okay I'm going to be a freshman and my boyfriend is going to be a junior. Well last week he was hanging out at my house and we were just chilling on the couch watching a movie. Well I got up to go get something and my phone vibrated, so as a natural reaction my bf looked through my texts. I had nothing to hide, I just don't like people going through my things. Well I was texting a guy that my bf hated and the message he sent was "you're so cute, when you break up with your scumbag boyfriend let me know", he read through all of our conversations and I didn't say anything wrong, or misleading, but when he saw it he completely flipped out on me. So basically our fight/argument
You're cheating on me with him, you're such a whore
No I'm not, and don't call me that
Well it's what you are
You shouldn't be taking your anger out on me when I didn't say anything wrong, you should be upset with him
You probably deleted all of the bad stuff off your phone
No I didn't, whatever you see there is what was there originally
I trusted you
I trusted you too remember, the difference between you and I is that you're the one that actually cheated, I never did and I never will
It was a one time thing get over it
Okay, well this txt only happened one time so get over it
You don't tell me what to do
And who do you think you are? You can go around sleeping with a bunch of your female friends but when I get one text from one guy saying something you don't like you flip out?
I never slept with them
You're a damn lie
He grabbed me and he hit me. Not hard enough that it left s bruise but he shouldn't have ever Put his hands on me. I've been avoiding him since and he's been blowing up my phone, facebook, twitter, tumble, myspace, email, my actual mailbox, with apologies and everything. I don't know what to do. Part of me wants to give him another chance because everyone slips up, but then the other part of me wants him to realize what he had and he forever lost it. I'm so confused. Help
