basically my relationship with her is 57, I already dedicated a tournament victory to her, I recited all the poems I can and I even joined the north just to ask Robb Stark if I could join his family to which he said yes. Now I don't know how else to improve my relationship with her, whenever I ask her if we have a future together I get the message saying that Ned Stark doesn't approve and when i tell her to leave together she refuses. I really don't know what else to do. I am playing on version 4.2 from Moddb.
You have to elope with her. She won't go with you if you don't have a keep of your own. Ladies need a home.
