need a spell

You'd need something that would make them have it on their mind. Perhaps a sort of binding, and when you feel they have realized their mistakes you can release?

yep. that's probably like it..
do you have any?

Aqeil it's best to learn your own spells by writing them. If you need a binding spell, just put what is it the spell you want it to do. I don't know much about binding yet. But it's not to hard to write your own spell. It will give you more experience in magick.

well o do write my own spells,
i just ask everyone..

First off let me say your approach is refreshing. Too many people come at things like this looking for revenge, trying to make the other person feel as bad as possible. You want to help this person, not hurt him/her. So on that note, you really want to be enforcing two thoughts. Not only does the person need to think about aforementioned mistakes, but this person should also feel they have the ability to change for the better. They must recognize both need and capacity.

This seems to be hinging on a person's free will to me. Which is difficult and not a good idea to affect. But you do have good intentions, it seems. You might try something that will "open their eyes so they can see". How they feel about it is all their own.

This is a spell I used and wrote. It worked very well on the person I cast it on. It also worked on my friend's ex boyfriend as well.

Theres many options in this, so which ever would best fit your needs you can use.

I would bind the person from harmful thoughts and actions before you cast an eye opening spell on them to see what their actions have done.

Well I know this is either your way of making this person come to their senses, but sometimes a person is not ready to come to that step yet and pushing them towards it, isn't going to to solve anything.
"The road to hell is paved with good intentions."

Just keep that in mind but other wise a binding spell would most definitely work well.

Merry Meet Ageil,

yes i have one but i have got it from this site, i was contemplating doing this spell on my now x partner.

the "spell to make some one understand you" may be of some use to you, and it seems easy to do as well but i have not tried this out as yet.
