Just consider it as an obstacle. Its not real and you and him are meant to be together. He doesn't love her, he loves and misses you.

Don't give it credit.

Read that again.

Don't give it credit. 

Now that that's out of the way, here is how it works.
Imagine your life is a straight line. You were walking on that line unaware of your powers as a conscious creator until, suddenly, your lover left you.

Now you're not walking on that line, but on a parallel line were you've made your firts approach to the Law of Attraction. Only because of that, your new path has a different ending than your old path. You changed your destiny by manifesting a breakup because of your fears, expectations and limiting beliefs.

Do you follow?

In fact, you were probably expecting your lover to find somebody else. You probably said it at loud many times, did you not? 

Not to blame you. I did. It's okay. You're on a new path now, and that old path has nothing to do with you. 

Now. As you grow, evolve and improve, you will be opening new paths, all of them with different endings, different results. Tell me, if you grow as a person a become a different being that the one that manifested the breakup, do you expect the same results? 

So, what you need to do in this new path: 

1) Forgive yourself for manifesting the breakup
2) Forgive your lover for leaving you
3) Take a look of your limiting beliefs that created those fears and thoughts

Common limiting beliefs: I'm not worthy of love, I'm not deserving. I'm not enough, He or she can find someone better than me, etc.

GET RID OF THOSE LIMITING BELIEFS.
Substitute them for
I am worthy
I am Love
I am Loved
I am Wanted
I am Worthy
I Am enough
etc

Now, tell me, as you grow as a confident person who knows his selfworth and who knows he's the creator of his life, would you still be on the same path were your lover leaves you and finds another person, or would you expect a path where that third person goes away and your lover comes back to you? 

Be better and expect better.


In the meantime, don't give any credit to whatever your lover is doing or not doing. This journey is about you. The more you think about that which you don't want, the more you give it energy. Change your focus towards yourself, your life, your passions, your friends,...and that unwanted circumstance will lose momentum and go away. 

You have to do nothing else but focus on yourself. At least for a while, until you find your self-worth.

Hope it helps
