Dont take my comment in negative way, but when you take their help results can be "Do or Die"
In short, either Satan will help you soooo much that noone can ever hurt you. He can 'reconcille' in minutes but then if your partener cheats or if anyone tries to hurt you for that instance, he is a goner!
Or you wont be able to communicate with him at all, because it needs a lot of spiritual energy and determination.
My suggestion : Simply grab SIGIL of a Daemon God who helps in such matters, and then ask for help...
And yes, Satan is very busy Daemon God, trust me :)
