The way you did your vision board in your relationship is like if you have a very unsuitable job in a crap company and you start to put on your board high salary and satisfaction, for example - it’s not gonna happen with this job. Also it comes down to the fact that your definition of a perfect relationship seemed superficial at best, though one would question what is even perfect. I don’t think the problem is with the vision board and manifestation but with your view on relationships - once there’s more growth there the technique might work better!
