Yes you should! But it all depends on who you are asking. for example if you already dated her that depends on who broke up with who. Like if she broke up with you then you should probably get back in the friend zone and move on your way from there. But if you broke up with her that may be much harder to patch up. Because she and most of her friends probably want nothing to do with you. But if you made an honest mistake it wont be long till she realizes that to. Sooo My answer is YES YES AND YES
