Should I tell him?

So I am in a new relationship, it's not even 2 weeks old, but I feel like I might have something very special with the guy.

And here's what happened. Two days ago, my friend, with whom I hooked up about a month ago (because he practically begged me to), tried to have sex with me, and he wouldn't take no for an answer, he pushed me on my back and tried to force himself on me. I told him very clearly I did not want to have sex with him, at all. And he knew that I have something going on with someone special. We were friends all through college. How could he do this to me? I thought I knew him well?

I had to literally scream for him to stop.

And later he told me he wasn't sorry that he tried to, I don't know, rape me?

Dude, I get you like sex, I like sex, too, I'm just not interested in you, at all. And not to mention we've been very close friends for a long time, it adds to the feeling of betrayal.

I feel so very disrespected and disgusted, and I don't know how to tell my man about this.

Should I even tell him? Will I look like I'm looking for attention? (I know I know it's sad I think that, but we're still getting to know each other, and I like him so much I feel self-conscious about everything.)

I mean, we're only starting our relationship, I don't know if it's going to mess it up. But I've been feeling like crap.

Btw, that so-called friend is no more.

I don't know. I'm so angry I can't even sleep, please help.
