Take LSD or magic mushrooms with her with several times, what would happen would likely be either two things
1) You two connect on a psychic level and she realizes how to stop being a basic bitch who watches dumb tv shows and realizes how she can be more intelligent and interesting to you and the relationship becomes something you actually enjoy
2) It becomes very apparent to both of you that the relationship isn't that great and that you are just not meant for each-other and would be happier with different people and it helps you two break up with less awkwardness and drama.
either one would be an improvement
