It seems to me that she may not be over your boyfriend and seems to be jealous of you, especially if you were somehow involved with him during their breakup-don't know if that happened, just would make her angry and hard to let go.  Its too bad if she is using the daughter if in fact she is playing games, it would be immature of her.  What are her intentions, If she is insecure and just wants to be like someone else she may just be looking to you.  If it is more sinister then be cautious, but don't give her your energy.  Focus your energy on the good in your life and your healthy happy relationship.

She is very sinister..That is one of the reasons why it is so hard not to focus on her...But everyone's advice here on this forum has shown "how not to handle" this situation no matter how difficut it may be.  In the future, I intend to focus all of my energy on improving my life and nurturing my relationship with my boyfriend.  As far as sending love her way, well, that's a different story..I will try my hardest but I think my best course of action, like I said before, is to focus on my life and not hers.  

If Karma is true to form, she will make her own life what it is...What one puts out, comes back to you threefold..If she wants to bring negativity into her life, she will take care of that herself..She won't need my help..Because of that, I wish her all the luck in the world...

Sending her loving energy, so she can heal, takes no time....seconds a day, and can be done without taking any of your energy away from the things you feel you need to do.  Just a thought.
