I know what you mean, I feel the same way about it, I've heard so many different things and some of it is contradictory. And it's hard to know who or what to believe, until something happens where I can see for myself. This is mainly regarding my ex but other things too. These things could take years to work out before I know anything for sure. So in the meantime it can be agonizing.
I don't think any of them can work a hundred percent, they are going to be wrong sometimes. Melody Marie has been the best for me but she has been wrong before. She hasn't done me any real harm by it though like other readers have. Some have really put me through the wringer, messed my head up, strung me along with false hope. The ones who can't admit they are wrong, or might be wrong, are the worst.
I hear you and I hope if you still want readings that you are able to find a good reader. Or if you don't that you can walk away from it without needing to go back anymore. Keen has a few good ones but they are so hard to find. Keen is probably the lesser of many evils but they are still kind of evil IMO. It's just too easy to go overboard on there.
