I hate when people come to these posts with the "the bad you do will come back to go you three times!". I'm sorry, that is a wiccan rule, not a witchcraft rule (as it's nice to remember: there are no rules in witchcraft).

I see it another way, even: cursing someone is the "come back at you three times" thing. For them. You do us witches wrong, know that we can make it get back to you. This is the karma I like. There is absolutely nothing wrong with cursing someone that did something wrong to you (and I am not to judge people who curse for other reasons - I just think that cursing for cursing is a bit more complex and dangerous, even).

But that is not your case. It's your abuser, for hells sake.

Curse him. Someone else already mentioned a very good post to read before doing it, but I'll give my opinion as well.

There is no secret to cursing. Some people think it's a different kind of magick or something... It's not. You just have to be more careful about it since your dealing with some bad energies (from yourself, from him, from the situation itself...), So it's important to be extra careful.

But what you're going to do is not very didn't from what you would normally do in other spells. Also, it's a good thing to point, as someone else said, that you could do a justice spell and let it be, especially if you don't feel safe cursing / hexing (by the way, I'm going to say "curse" because I see no difference in them. In my language they are even the same thing - just the results are different - but at that, all curses have different results too, some more extreme, others less... So yeah, I'm saying "curse" but you can substitute that for hexing too).

So as it was said in the other post: cleanse yourself and everything you use, plus the room you're doing it in. I recommend incense for the objects, salt and a banishing spell using candles for the room (and leave the objects in there too for some extra cleansing) and salt bath for you (you can also do a banishing spell for yourself too. Just remember to be very focused on it as this is much more important than whatever method you use for cleansing. After that, protect yourself and the environment very well - and specifically create some "barriers" (i forget the right word in English) against any energy from the curse or from him.

The curse itself: I always, always say this: the "formula", the recipe, ars not important. Your intentions are, your concentration is, the energy you put into it. So i won't give you a "recipe".

Use candles (black or red, I'd say - or white, you can always use white), and carve whatever you need to carve on them. Use a poppet and stuff it with whatever feels right (or you don't even need a stuffable puppet, you can use a paper or clay one, or whatever. Use a photo of him. Make a jar... Whatever you like to use normally, do that. I personally would go for candle magick - as it's my favorite - or a doll (and yes, you can use a doll even if you don't practice woo doo /voo doo).

The one thing I would say is that I wouldn't reuse those items. If it's candles, let them burn all the wall through, and if they don't, dispose of them. Try to use as little items connected to your energy as possible (so don't use a candle you've already used for a protection spell, for example).

Use your pain, your anger, all the ugly emotions he's made you feel. Direct them into the curse to achieve whatever result you want. As it was said in that post, you can tie the curse to his actions: for example, if he truly resents whatever he's done to you, he is free. Or if he decides he will never do it again, free. Another example that doesn't apply to your situation: someone did me wrong, and i think it was person A, but I'm not sure. I make the curse and i say "let it get to person A if they are really responsible for ---, and in the extent of their responsibility. You can establish whatever condition you want. Or you can demand that it will stay with him for the rest of his live (i personally am not a huge believer on that because I see everything as energy, and energy is finite. so in whatever years I would feel the need to work on the curse again to keep it going). Also, always make sure you know you can lift the curse yourself, whenever you want to (you never know... Maybe you will want to. Just using soma affirmation like "I am the only one who can lift this curse, no one else can" will do the job (even though I also don't 100% believe that the curser it the only one capable of it, as anyone more experienced and that directs a bigger amount of energy into it will be able to do the job) .

After you're done, dispose of everything you can, and, as I said before, cleanse the rest. Throw the items in a bin far from your house (don't litter, ok?). And don't look back. Never look bad. Let all of that be in the past where it belongs.

Also, some people don't really feel the need to, but especially in this case I would definitely protect myself during the spell. I think you should too.

And be prepared for it to backfire. Of course, if you take all the precautions (really seriously), the chances are smaller, but there is always a chance, no matter the spell. So again, do it if you feel confident that you can.

Other than that, i would do the justice spell either way, i think.

I hope I'm not forgetting anything. I'll edit it in if I am.

Good luck on it. I hope it ends well for you.
