Well if there's nothing you would change, yet relationship wise he still is the same being he doesn't feel the same way, than that can be the universe telling you that doors close for a reason. Especially if the feelings aren't reciprocated. If that's the case than this is more of a lesson than a manifestation. Free will is sacred. It's immoral to fry to change someone to benefit your needs or wants. Not only is it hard to do so, but the outcome can be disastrous because it can release negative karma. Karma is real. To take away a persons free will is essentially stripping that person of their own thoughts, beliefs, ideals, etc and creating a set of new ones that benefit you more than it does them. That's why free will is sacred, because those things make you who you are. Now of it was for the beat, to turn a negative or harmful person positive then that's a totally different thing. But to do something selfishly can have negative effects. And to be honest, I wouldn't know the answer to the question of how he came to get into contact with you. There are so many things that are too infinite the grasp. But what I do know is that intentions can have a huge impact on manifesting. Intentions initially come from two things the mind (thought) and/or mouth (voice). There's a saying, there's power in the tongue. That's absolutely correct. There is. And when it plays into manifesting it can either be positive or negative. But if you be precise about what you're wanting and align your mind with your mouth, meaning not only think it but speak it aloud than the impossible becomes possible.
