sorry if what i say hurts [i'll try to be gentle] i understand you love her, but she does not love you. find inner peace and happiness with yourself, don't define your happiness through this woman. people fall in and out of love all the time, it hurts [for how long depends on the person] you tried fighting for her, but its clear she doesn't wish to be with you at this time. breathe. try to relax, and move on. it sounds harsh and hurtful, but if its meant to be she will return in her own time, you should focus on healing yourself right now.
while fighting for her and trying to get her back is fine, what you did wrong was threaten them with the 'wrath of god'. you spoke out of emotional turmoil, but when emotions get the better of us, bad things can happen, so the law takes things like this seriously. walk away for a time and heal.
magickally you can do a cleansing for yourself to remove the negativity that is weighing on you. meditation, balancing your chakras, and other exercises to bring insight and peace would be best. once you are centered, reflect on her, and if you still want her back, try talking with her one one one [calmly is the key] if she still says no, move on [or look into love spells but thats a bad idea] good luck, blessed be.
