My Theory on Ashara Dayne and Wylla the wet nurse of house Dayne [Spoilers EXTENDED]

[Spoilers EXTENDED]

My Theory:

During Harrenhal Tourney’s Ned Stark and Ashara Dayne fall in love and plan to marry (since then his elder brother Brandon Stark was the one who was betrothed to Catelyn Tully) Rhaegar Targaryen, Lyanna Stark, Oswell Whent and Arthur Dayne flee to the Tower of Joy (Arthur brings Wylla to help Lyanna with the birth once she becomes pregnant) Brandon Stark wedding party is traveling from Winterfell to Riverrun when Brandon gets the fake news that Lyanna was kidnapped (Littlefinger might have something to do with that) Robert’s Rebellion happens Ned Stark marries Catelyn Tully to secure Tully alliance, Tower of Joy Battle happens Ned Stark finds Lyanna with Jon Snow and Wylla goes to Starfall where he lies to Ashara Dayne and tells her she can’t marry him, Ashara Dayne commits suicide
