While I kind of agree with you about parting ways... But not wanting something isn't really a "need"... Especially since it wasn't disclosed before the relationship started..
From her standpoint, it's like buying a blue car with leather seats that turns pink with white satin seats after 3 years... You hate pink and it won't change back to blue even though you try to repaint it again and again...... So trade it in on a new one... Or run it over a cliff!! Lol.
