You know that you are the creator of your own reality, so why are you worrying about anything? It's in your control and if you worry you attract it, so let's think more beautiful thoughts.

I have to admit that I was a bit surprised that you managed to get your ex back even though your vibration didn't really seem to be in the right place. So I'm not really surprised about that he is gone again. But do you know what the good thing about that is? You know how to fix this situation. You have to work on your vibration. You have to become emotionally and vibrationally more stable. You can't just think all over the place and expect things to work out. Strengthen your focus. Concentrate on what you want. When you can get him back once, you can get him back twice. But this time you have to become a better version of yourself first.
I would recommend to concentrate on your own happiness for a few days and don't think about attracting him at all. When you feel better you can start your journey again.

It's weird because I know I can have him back and I don't know why I can't think otherwise. I guess since it all just happened it's hard for me to get back into a good vibration.

I absolutely agree.  Love yourself.  Your amazing.  There is only one of you.  Make him want you.  Be amazing.  And take back the control.  Make him miss you.  Don't chase after him.  Ignore him and focus on yourself and love your life.  Good always prevails over the bad.  This other woman is not you.  We are all unique.  I did the same as you thinking I was just average to my ex and I lost that I was amazing and he lost interest and I became more needy which pushed him away.  I know I am amazing.  He I know is kicking himself and he is working on himself.  Because the loa is fantastic.  It won't let you down.  But you have to really want to work on it.
