Anything is possible! You just have to know your desire. For me doing it a second time was really hard because I had to come to terms again that not only was this breakup worse than the first one, but I just didn't believe in myself. And it wasn't a product of what my Love was doing, it was my fault. It was harder to forgive, harder to remain positive, but I'm currently  manifesting my amazing relationship for the second time. Don't give up-a true LOA follower would never tell you that. Your thoughts create your reality. So you already know what you did to manifest her the first time, do the same but this time really work on yourself. Let it go and it will come back in a way that most certainly pleases you. It wasn't overnight, it was a lot of tears and work to change my perception. I once read that it doesn't matter how many times you break up, when the love is true you will always find yourself back together until you get it right.
Also, let yourself feel your feelings, I really recommend that because now when those doubts come up there are no feelings.associated with it, I know it is just my fear and that it isn't really how I feel.But you have to work through the current reality and get back to the place that you know and believe you are meant to be. Stick with it if it something you desire because the Universe knows what you truly desire no matter what they say.

I think the very first step here is to think about what thoughts caused the relationship to fail and work through this, else the same thing will happen to you over and over and over again. Of course you can attract her back, nothing easier than that. But what is the benefit, when you haven't learned anything and the same thing starts all over again? A breakup is an amazing opportunity to grow. Take it and learn everything from it you possibly can learn. Do it for you and not for her or anybody else. Make your goal to become a better person, a better person, a better friend for yourself.

There is nothing like "meant to be". It completely depends on your vibration. It's completely irrelevant what she said or did or whatever. The only cause for everything are your thoughts. So, when you change your thoughts, your reality has to follow.

I'm afraid we can't help you building faith. We can answer your questions, we can tell you over and over again that your circumstances don't matter at all, because it's just a reflection of your state of consciousness, but you have to do the work on your own.

When you read a few of my posts, you will find that I never use the word faith. Why? I think it comes from a very physical perspective that doesn't help you with LoA. You need faith, when you look at reality, take it as the truth and hope that it will change, but you can't win from that perspective, because it always keep you stuck at where you are without your desire. You can't change reality, it's an impossibility. You can only shift to a different reality and if you want to do that, you can't pay any attention to your now reality.
You don't need faith. You need knowing that this reality is only a reflection of your state of being, of your past, that it means nothing and that there is no point in thinking about "reality". You have 60000 thoughts a day and you can spend these thoughts thinking about reality and by doing so, keeping it exactly as it is. Or you can say "screw you reality" and live your desired state now in your imagination. If you could do that without wanting to change reality, without wanting to make something happen, just for the joy of it, it would happen fast.

It sounds easier in this terms, but what I mean with faith, by the way, is: does loa really work? It's just this question. Even if I won her back once, I still have doubts. 

Of course it does, in every second of your life. But you need to experience it yourself. It takes time until you are convinced.
