Sooo many things:
Fairy tales are just stories
Always stay financially independent
You need to feel lovable, loving and loved
Trust those who are trustworthy
Don't rely on others for your own sense of worth
Learn to communicate with others clearly
Value your own thoughts and feelings as highly as those of others
Love is not falling in love before you have any real information about who that person is and what they can contribute to your life
Relationships are made of two equal, distinctly separate beings that enjoy each other
If it barks like dog and looks like a dog....
The most important relationship you can have is with yourself first and foremost
Extreme loyalty is not a virtue
Learn what your boundaries are and that it is ok to enforce them
Learn to listen and believe yourself
Believe someone for the actions they take not the words they utter
Don't be afraid of change or being on your own
