My girlfriend brole up with me and I am crushed?

I messed up with everything and I thought we could work through things but she ended it. I send her a text 1 week after the break up that I want to fix things and apologies if I came across in a bad way. That i still care about her deeply I miss her. She hasn’t answered me. She ignored me. I want to send one more casual text in 1 or 2 weeks. If she doesn’t respond I am done trying. Its my first girlfriend and the break up is really tough. How do I deal with it?
