That page of black spells that Miss Aida linked for you has a lot of useful stuff, and the work you describe with the D.U.M.E. candle, goofer dust, etc., sounds solid, and so does the vinegar jar. I thought I'd add though that if you want to get this guy exposed once and for all for the pedophile he is, you could check out this forum thread:spells-to-get-criminals-exposed-arrested-jailed-imprisoned-t8951.html
I'll also say though that obviously I don't know your entire situation, but it concerns me that you feel like you have to talk to this guy and say you love him, even when he's doing all these awful things, threatening you and being physically abusive (slamming on his breaks so you hit the window). You don't deserve that. You deserve happiness, love, respect and a guy who isn't preying on young girls. Just from the brief things you posted on this forum, I fear for your safety. Please watch out for yourself, and don't just rely on hoodoo when you really need to just call the police.
If this is all too much for you, and you feel like you could use some extra help, you could hire a rootworker to work on your behalf: http://readersandrootworkers.org
Good luck to you, and take care.
Thank you, St. Michael, St. Expedite and La Santisima Muerte!
