Because you LIED. She flat out asked you if you were upset and you lied. I understand why you're angry... if she truly blew you off. She may have had things to do those 4 times.

It could be for a number of reasons. One, you told her you never wanted to see her again, that's pretty harsh considering you broke up with her just based on her unreliable personality. Second, you broke up with her through text, which is a sign that you were too nervous and afraid to break up with her in person, probably because you then would have had to have dealt with whatever emotional backlash she was going to hit you with. Lastly, after she replied to you, you told her to fuck off and never text you again, that is just like adding fuel to the fire.
