Lets see how many of these stages I have experienced thus far…I am especially positive I have experience #2 !!!!!! http://lonerwolf.com/twin-flame-stages/

“The love experienced between two reunited twin flames is like a wild beast.
It can’t be captured. It can’t be contained. It can’t be tamed. Instead, it burns fiercely with an unquenchable form of intensity that is both exhilarating and formidable. The love experienced between twin flames is like Holy Fire: it burns you to ashes, but it also forges you into a new creature, like a Phoenix emerging out of the dust.”

Stage One – Yearning for “The One”
In this preliminary stage you have spent your entire life pining for “The One” that doesn’t yet exist in your life. You have this strange sensation that someone who is perfectly molded to you is “out there” but you don’t quite know where or when they will appear in your life. Although you ache for your twin flame, you have a feeling they will appear to you at some point.
This stage is also sometimes spent “preparing” for the arrival of the twin flame on an unconscious level. In my instance, I had to learn how to love myself before I met mine. For others, this stage of preparation involves the development of self-awareness, discovery, and understanding.

STAGE 2 – Glimpsing “The One”
At some point, you will have a brief glimpse of your twin flame. Whether this is through a DREAM signal, or through a real life meeting, suddenly the Beloved can be sensed. The result is profound. Wonder, joy, anxiety and intoxication quickly ensue. For those cautious among us, a lingering sense of intense curiosity and desire to get to know the person better is the result. You don’t know what it is exactly, but this person is extremely special. Like me, you may even sense that this person will play an immensely important role in your life – even before you know them properly.

Stage Three – Falling in Love
When you fall for this person, you will fall very, very hard. You will fall harder than you have ever fallen for anyone – and the impact will knock the breath right out of you. In fact, as you get to know your twin flame better, you will fall more and more deeply in love with them. As a result, you’ll find it hard to stand with two feet on the ground. You might feel disorientated, lovesick and “unlike yourself.” You may even try to resist the attraction, but eventually you’ll accept the reality that you’re deeply and madly in love.

Amazing stuff.
