Unfortunately, magick would not be the good choice for this situation.
Using magick in regards to love problems will result in taking control of the target's free will. This will ultimately leave you in a worse situation than you feel you are in now. If you want to love this woman right, please refrain from magick. Also, are you saying that you are, "wanting to spend the rest of your life with her because of her abandonment issues?" If that was said how you intended, then that would be slightly unhealthy and very unfair to her. Use time, dedication, and patience to get you through. She will need professional help in order to be comfortable.
