“I don’t see it manifesting” is where you’re going wrong. You’re focusing on what you see around you. Stop looking at your reality like it is and start seeing it how you want to be. So long as you focus on your reality, your thoughts are filled with your current reality, and that’s what you are creating – more evidence of not being with him. Simply put, you are not at one with your desire. You have to change your thoughts. You need to be able to relax and let go. You need to make sure you aren’t obsessing over things and trying to control the situation. You need to focus on raising your vibrational energy and doing things that make you feel joyful. This article on resistance might help you get clearer so you can attract a specific person.
Skeptical Inquirer magazine criticized the lack of falsifiability and testability of these claims.[47] Critics have asserted that the evidence provided is usually anecdotal and that, because of the self-selecting nature of the positive reports, as well as the subjective nature of any results, these reports are susceptible to confirmation bias and selection bias.[48] Physicist Ali Alousi, for instance, criticized it as unmeasurable and questioned the likelihood that thoughts can affect anything outside the head.[1]
If you’re serious about growing yourself into becoming the kind of person that you want to attract, then I recommend that you cultivate a network of therapists, counselors, coaches, healing professionals, trusted friends and mentors whom you can count on for any variety of challenge that will arise.  Especially when the big stuff starts coming up, and it will!

The process of attraction happens at the level of what we feel and believe, and when you don’t set standards and boundaries, this shows you don’t feel very good about yourself, and that you have a lot of crappy beliefs that essentially amount to not feeling good enough, and not being deserving of the best life has to offer. These types of beliefs can mess with various aspects of our life, but can be particularly problematic in the love department. And guess what types of people and situations we attract when we feel this way? Shitty, shitty, shitty ones.
When it comes to interest in law of attraction, I would have to say the two things people are most trying to get is love or money, perhaps both at the same time. Relationships can be a tricky area of manifestation, not because it is inherently harder to attract them than other things, but because of all the ‘stuff’ we have built up over the years that lays heavy in our vibration. We have all sorts of beliefs that tell us we aren’t good enough. Our past failed romantic endeavors are etched into our minds, and we are convinced we can’t experience anything different. We worry we will never meet someone, or that we will have to settle for less than what we want.We stay in relationships that we know aren’t right for fear we won’t find something better.

This entire reality is your creation. Feel good about that. Feel grateful for the richness of your world. And then begin creating the reality you truly want by making decisions and holding intentions. Think about what you desire, and withdraw your thoughts from what you don’t want. The most natural, easiest way to do this is to pay attention to your emotions. Thinking about your desires feels good, and thinking about what you don’t want makes you feel bad. When you notice yourself feeling bad, you’ve caught yourself thinking about something you don’t want. Turn your focus back towards what you do want, and your emotional state will improve rapidly. As you do this repeatedly, you’ll begin to see your physical reality shift too, first in subtle ways and then in bigger leaps.

While there have been countless books, audiobooks, articles, television shows, and of course, blog posts, on the topic of success in life, most people still feel lost. There’s a day-to-day struggle that many simply can’t rise above, suffocating in a sea of despair, hopelessness, and lost dreams. But, there must be a way. Surely, if others can do it, we can do it too, right?
