Would you forgive your boyfriend for calling you a whore when you are faithful and honest?

I have been with my boyfriend for 3 years. We have lived together for 1 year. We recently have picked out an engagement ring and planning to get engaged by the end of this year. He has always told me everyday how much he loves me, he always wants to make me happy no matter what. And stupid me....I fell for it. He was drinking this past weekend and he came into the living room and out of the blue he tells me this...."You are a whore, you were a whore when I met you, your a whore now, and you will always be a whore!" We weren't even in a heated argument. I was completely blindsided by this. I haven't spoke to him in 3 days. I can't breathe when I think about it. I am beyond hurt. This is the first man I actually have been honest with and have let him in my personal life. He keeps calling my cell and leaving me messages of how sorry he is and he didn't mean it. I don't know what to do because the pain of this is unbearable. Not only does this comment let me know what he thinks of me, but it shows me disrespect. No one has ever said anything so hurtful to me ever. What would you do if you were me? Remember, we live together but I am not sure I can get past this and forgive.
