There most likely is, but you have to consider this first. I assume you have questioned the just-ness of love spells. I don't know what conclusion you brought yourself to, but I personally don't agree with them. But only for the reason of tampering with free will. So lets compare the two spells. Love spells force someone to abandon that one true love they were destined for in replace of an inflicted other. So basically, that person in forced into a relationship that otherwise never would have happened. Now a friendship spell, I personally believe follows the same idea. If you cannot seam to work out an issue with friends, maybe instead of forcing them to like you, you should be questioning there compatibility with you. Some people just don't belong together. That doesnt make you or them bad in any way. Its just a personality thing.
And, yes , I did read what you wrote about already trying to work it out verbally, but if they truly mean that much to you, you will keep trying. So just think about that, because spells cant fix absolutely everything.
But hey, if you don't agree with me, that't perfectly fine. Disregard everything I said. I just think its better to see a problem from all angles before persueing something that can't be taken back.
Good luck, I hope you work something out. :)
