Hello Apple, and welcome to the site!
Personally, I'm glad you have decided to forego the love spell with your ex (I'm assuming they are your ex now by what you have said). Love spells can work, but it has been my experience that when you try to regain a lost love it has a tendency to backfire. In my opinion it is best to let nature take its own course when it comes to exes. Though there are those that deal with these types of spells I do not personally feel it is a good idea to meddling with anothers free will, so to speak. More often than not, it has a tendency to incur unwanted effects, sometimes devastatingly so.
As to your latent abilities, meditation is a good place to start I think. You may also want to find someone who is good at reading people. They can often sense gifts in others, and may help you discover powers within yourself.
I feel it's best to go with your natural inherent abilities first (even if it's not healing). You can always learn to play the piano, but that doesn't necessarily mean you will become a concert pianist. :) Developing the talents you are drawn to naturally first will in turn make it easier to practice other things, even if you never fully master them.
I hope this helps!
Peace Be Yours,
