Im really sorry to hear about this.
there are some things you can do, but like a lot of people have said, they tend to backfire.
whatever you do though...dont pay anyone money...DONT...there are so many people out there looking for someone hurting so they can take advantage.
as far as what you can do, you have to have the basics down first and then if youre going to do love spells be very aware of not becoming obsessed and letting things go so the spell(s) can work.
Since shes with someone else youre gonna be breaking up another relationship...which could mean affecting a lot more people.
I dont know what path you follow...but unlike others, i say go for it...just be aware that you have responsibility because of what youre doing. Do as you will, just be preapred for the consequences......and dont forget that magic is an energy that will make the odds better....if this situation is "impossible" then it wont work out.
Anyway, I really fell for you. Divorce is horrible and the pain can be nearly unendurable.
Whatever happens, I hope it works out for you. And it will...
