In twin flame relationships or any type of higher spiritual relationship, its always acknowledged on both sides, not one person chasing and stalking someone who wants nothing to do with them. Theyre rare and youll always be sure of how the person feels on an energetic level even if its not verbally expressed. If you have to question, it's not real. That's the easiest to decipher between higher vib relationships and lower vibe ones. Higher vibe ones, youll know how the other person feels and nothing can make you change that and the relationship makes you want to better yourself. Doesn't mean all higher vibe relationships are easy, usually the contrary because of all the clearing that must be done between the 2 souls. Usually, the karma accumulated over lifetimes that the individuals spent together. Lower vibe ones fill your head with doubt and youre always questioning yourself and the other person. Takes away your energy, power, and brings out your worst characteristics over time. And then there's just the normal relationships lol, where there isn't much clearing to do and mostly based in this lifetime and 3D. Just what I believe. I don't believe every relationship has a past life link. I also don't believe in what a lot of TF readers will say about talking to the higher self of a person you haven't met yet or anything of that sort. I believe people are brought into our life by destiny and what happens after that is a mix of destiny and free will.
