No matter how much you try to look for outside validation, you know the truth of your connection by trusting what you feel within you. No matter how many people you go to for affirmations, you know what you believe and what you feel.
No one can know how you feel. No one can tell you what to feel. And no one can make the connection happen if it does not exist naturally.
Also, as someone who struggled with finding out what was happening to me when I was new to the experience, I understand your confusion. It takes a while to have a hang of the Twin Flame experience but soon or later, you find your compass.
Your compass is your inner knowing. Trust how you feel.
