Hello Friends!
Last month i did my first spell!
Now i have had lots of practice with astral projection and deep meditation and have been reading the book "Modern Magick 12 lessons in the High Magickal Arts" as if it was my bible.
I cast the spell on Oct 29th 2014, This spell was a Lust spell originally but i added love into the mix as well. Now this is my story and what happened.

I did the LR ritual ( Lesser relaxation ) and got my body completely relaxed. After that i did the LBRP ritual (Lesser Banishing Ritual of the Pentagram)and then cast my circle. Then i did my spell. I felt good about the spell and everything went smooth and very well for i prepared my self for this spell and came into it strong. Now exactly 5 days later something huge happened! My targets Husband got into a horrible car crash and died. Now i don't know what to say.... Did i do this? The chances of that happening are very very slim! I have felt bad for the last month so i have been very supportive to her and her family. Yes its true thing are starting to develop and we have been getting closer but i feel bad inside about the hole thing and felt i needed to share this with others.
My question is how long do spells last and do they have an exasperation date? If her husband died was that partly my fault? Can a spell partly work? Can spells take a long period of time to complete the final out come? Should i be concerned with my own spiritual karma for the out come was not what i intended and was only a test, yes i care a lot about the person i targeted and we have been friends for a very long time and i could see my self with her but i did not intend for a death.
I know it was selfish and have grown from the experience.
Thank you every one who comes to read this and any answers to my questions or insight would be greatly appreciated.
Thanks
