Dont give up hope on yourself. Be patient and keep fighting. Also let yourself be happy dont be an idiot. If you drop her its would be the same as locking yourslef out of heaven. You will never forgive yourself that. If shes with you that means thats what she wants and its her choice shes and adult. The negative emotions will come from parents so you dont have to be worried about that, just be happy as long as it lasts and dont question love so it might last forever. Cruches is much better than wheelchair so be happy about that.
