Is it to late to press charges?

Last night my now (ex) friend came banging on my door because he was mad at me.

He asked through text message why I didn't like his girlfriend and I respectfully responded that he deserves so much more than a woman who doesn't see her kids and lives off his money..sells her kids food stamps for drugs..blah blah blah. Turns out it was her messaging me the whole time. She told him about it and he came banging on my door and when I opened it he grabbed me by the throat and slammed me against the wall. My boyfriend intervened but not after I scratched the hell out of his face.

My throat hurts so bad today...I should have called the cops last night but didnt. Is it too late to press charges?
