Can feng shui help? Yes, it can. Feng Shui can always help attract the energy of love into your life; however, we cannot make it "person-specific."
For the energy of love to find its way to you, you have to be completely open to love, while focusing on a specific person restricts the flow of love energy (please note this is different from focusing on specific qualities you want in your mate.) Why? Because it steps into the personal energy boundaries of another person.
Your old flame might be in the same emotional space as you are, or she might have chosen a different experience; it is her own path. Being true to your own path, though, means you are clear with where your energy goes, and this is where I strongly suggest you open your heart to her (if this is possible) and clear out the "energy residue" between the two of you.
Even if this relationship cannot be rekindled, it is an act of blessing to reveal the love that is still there; and then, by being released, its energy will find the right course for your own highest good. However, if the strong love bonds are still flowing in both directions, you might be in for a great and beautiful surprise!
Feng Shui-wise, I highly suggest you focus on strengthening your own energy, as well as on opening your space for a strong flow of the energy of love. See this info on feng shui for love:

Only a healed and open heart will allow you to accept, cherish, and keep love, no matter new or old; and feng shui wisdom is always there to help you attract and nourish the energy of love.
Hope that helps and many blessings to you!
