You and Aemond were betrohed since you two were just children of 6 years old, his mother, the queen and his gradsire the kings hand always disliked you for being daemon targaryens daugther and since the incident at driftmark some years ago where aemond lost his rigth eye you two didn't see eachother anymore..but as the both if you finally came of age you both married for the sake of bringing the family back closer again and for the political reasons..even tho you two did not 'like' eachother..
