You cannot make anyone do anything against their will.
If the breakup was cordial, you can always get in touch with her and ask her how she is doing, etc.
If the breakup was not cordial, and you feel it is due to you being in the wrong, perhaps an apology would be in order.
Once you have broken the ice, you can ask if she would be interested in getting together to talk, or go to dinner.
If she says no, then thank her and leave her be. The worst thing you can do is make a pest of yourself.
