@mattyworld12 – Depending on how long you were together and if the relationship was more happy and satisfying than not, will more likely determine if there is a chance for reconciliation.
She did say she doesn’t want to get back together, but maybe that was said in anger or disappointment, I don’t know as you didn’t list the reason for the breakup. But if she continues to be adamant about it, you have to accept the breakup as final.
You could send a quick apology, but she might not respond.
