The separation phase can be a blessing in disguise. You sometimes both need a breather. A neutral space to figure out what is going on. At least that is how I like to see it.
When a Twin Flame has an aversion towards you, it seems as if he or she does not want anything to do with you but it is not the case. We all have different ways to handle stress especially the chaos that follows suit after the initial encounter.
I too felt frustrated when my Twin Flame ghosted me. I could not believe that someone who I thought completely knew me suddenly and instantly grew cold overnight. I could not wrap my mind around the whole drama.
As time passed, I realized that I was my own problem as much as he is his own. We both had to figure out what was wrong within us.
We both got scared of the connection. For me, I had deeper issues to confront. Why meeting him revealed all the demons within myself that I had hidden from for so long. I blocked him thinking that all the pain he had uncovered would go away too. His absence only reminded me of what I had encountered. A Twin Flame.
I wished there was a spell to bring him back. To fix us. I prayed to God to make him realize that we have a special connection. Hoping that he would come to his senses but his returns were unpredictable and scarce.
