Firstly yes,  you are creating resistance by looking for signs.  You know how they say a watched pot never boils?  Same thing.  If you're looking abd waiting,  you create more circumstances that leave you looking and waiting! Yes, it is common to hear from other loves or old friends when you raise your vibration. But checking status and trying to ASSUME or assign meaning is not a good idea. It can easily throw you off balance.

She left you because you attracted that behaviour from her. It's actually not her fault. So you need to reconcile that in your mind and understand that she was just playing the role that you presented to her. For her to leave you there HAD to have been fear in your vibration. So forgive her, this us about you and your fears.

Once you truly understand that you are in control of creating everything, then you're all set to begin manifesting the relationship you DO want. But it can't come from a place of need. It has to come from joy and happiness. That's why I suggest that you simply assume she's crazy in love with you, and she is thinking of you day and night! Don't look for messages right now. Focus on creating that reality in your mind. Also practice gratitude and appreciation every day. As you do this you raise your vibration. And with a higher vibration comes more faith. And then her text will appear as if by magic. Ok? So what are you going to assume while she's away?

If scripting makes you feel great, script! If it feels like a chore, then you are trying too hard so you should do something else that you enjoy.  We aren't worried about not hearing from her,  that's old news-stop bringing it up already! 😜 When you are busy getting happy and learning LOA with your forum friends here,  you won't notice that she's not texting..  And THEN she will text.

The excitement and energy you just poured into your manifesting story- that's EXACTLY the energy you need to emulate in relation to your girl!

That's exactly the energy you need to have when you are manifesting your ex. You need to continue on with your day with something else that you enjoy. To me, it sounds like work is the way to go. You are passionate about your work in trades and that makes you happy. You need to be working on a happier version of yourself so that she will want to be with you in the future. Try not to have any negative feelings nor doubts this will work out All is good and you have a future with her already, she is just on vacation.

It's also worth noting that I've had many amazing manifestations turn up into my reality without any signs. Sometimes they just go "yup, I've arrived" without any hints.
