I've been dating this girl for a while and i really, really like her alot. But the other night we got into a fight and I said the one thing that was the cruelest and most devasting thing I could have said to her. It made her cry and I've never seen her do that before. She won't even talk to me. How can I get her to talk to me? Is there any chance I can get her back or is it too far gone? If not, I could use some advice.
