Having experienced (what I know now is) Limerence, and now being in on a Twin Flame journey, I can say that both share some similarities, but are also two completely different experiences.
My Limerence experience was filled with the constant yearning, chasing, passion and what felt like a “meant to be” connection. I always wanted to be near them, and could never quite push them away no matter how I tried. But it was also a connection that brought out the worst side of me. I think the most important difference is that with my Limerence connection, there was zero spiritual awakening, no moment of “this feels like home” or peace. It felt constantly chaotic. And most importantly, despite the intense pull I felt in the beginning, the connection faded after time. There were no signs or synchronicities, and that desperation to be with them gradually disappeared. The entire experience spanned nearly two years. We ran, and chased each other; a dynamic I guess is similar to what I experienced in my Twin Flame journey, but with time, it gradually just went away. And once the entire experience was over and I finally walked away, that was the only moment I felt peace.
With my Twin, from the moment we reconnected (we are each other first loves that hadn’t been in contact for 22 years), the signs and synchronicities already started even though at the time, neither of us were aware of what Twin Flames were. I don’t think that he is aware right now, but he was actually the one who use to tell me things like, “Don’t you see the signs? The numbers that appear around us, and the songs that randomly play?” Back then, I didn’t even realise those were synchronicities. But he was the one who made me aware of them. When we look into each other’s eyes, the energy is so intense that we end up either smiling like crazy and laughing, or tearing up. It’s impossible to hold each other’s gaze for too long a time. Also, after our reconnection, it brought up a lot of wounds from my childhood/past that I hadn’t realised weren’t actually healed. I also went on a long spiritual journey where I started becoming more curious about other religions and beliefs, it made me question things but also helped me understand myself, God and the Universe better. And most importantly, he has always felt like home to me. Despite us being in different countries now (we haven’t seen each other in 1.5 years), and just going through 10 months of no contact, the love I feel for him has not altered or changed. The signs and synchronicities have gone through periods of intensity and quiet, but they have never stopped. And most importantly, I have learnt how true real unconditional love feels. Because when you don’t have physical proof, all you can rely on is faith. I think that is, personally, what my own journey has been about.
