If you're looking for self-help advice: I think you haven't established that true internal trust yet that makes things so much different (complete?). Start adding deposits to your emotional bank account. Focus on giving which is very easy if you love her. Stop focusing on getting. Give unconditionally for several weeks/months. I'm 100% confident she'll return if she loves you that much too. There's hardly anybody else in her life who does the same and people recognize that (sub)consciously.
