You have to be a male character to complete this romance. Morrigan will join your party after completing Ostagar. Be kind of a prick to other people to gain points with her. Have conversations with her about her past in the Party Camp. Don't get her romance level up too high. Morrigan is interested in flings. She doesn't want to be in love. See Hopelessly Romantic for more details.
