Wow.. what a *****. (sorry., but she's radiating negativity and anger from every angle. -Full of spite, and that's just downright terrible.. her taking it out on you ! ) I can understand her point of view., but as a grown woman. she should grow up and realize the damage she is doing to herself and everyone around her ! especially her children ! Problem is with her ex. not you., she should consider moving on and healing herseld., instead of seeking revenge.. because it always ends bittersweet. Like was already said, I doubt she's wiccan. Wicca is a religion, and the things she's doing go against several of the 'common rites' that many wiccans follow. If she's calling herself wiccan., then she should be downright ashamed - to be doing what she's doing.. With that said, she could just be praticing witchcraft., and her friend may be a witch of the sorts, but that doesnt mean she's wiccan. Regardless, the sage smudging is quite common amongst other cultures., with the intent to rid a space of negative energy or anything harmfull., (you can do this as well., no harm done here.. if you like of course., smudge the entrance of your home. and each room. along with yourself if you like of course. 'White Sage Sticks' are normally used for this. ) The same can be done with salt (some prefer sea salt) would be placed on the entrance of doors and windows around the house. (if you do deciede to do any of this, make sure your thoughts are focused towards removing any negativity that may be lingering in your home. 'in with the good, out with the bad' - in a sense.) some/certain rrystals, candles, and/or herbs of the sort may also help you if your interested in protecting yourself with the same fire she's fighting you with. I'll admit im somewhat concerned about the locket that she has.. because it has such a personal significance to you. - and with all that she's done already.. there's no telling what she may do. Is it possible to confront her ? - if she does gives it back.. i wouldn't put it on... there is lots you can do, to prevent anything harmful happening to you, or your loved ones. But I would rather not go into too much detail on a forum. overall, stay positive. She cannot and will not control you., feel free to contact me, if need be.
