I just read about Squiggy and I was super excited to see your post. Unfortunately, it wasn't what I was hoping to read about. Sorry girl.
To RAI's point I think when people like us (LBH S) go into relationship we are emotionally fueled and often clingy, we take own too much blame, and we don't implement the correct behavior to improve our chances. From that perspective your post did align with some of those behaviors.
However, honestly I think you needed to do something. I don't think it was the best interaction, but I don't think it was the worst either.
But in regards to this "If I were to say I'm sorry let's reconcile what would you say?" I said it's not that easy. He said yes or no, I said yes. I just don't thinks he sees any possibility for him to "be in love" with me again." I wouldn't fight your stance of what you believe. But I wouldn't openly admit it either. You need to VALIDATE him and suggest the idea that it is possible. Do not plead, beg, etc.
As for the email to him... I suggest writing it down on paper for him to find. Also, use this quote somewhere.... You could state how you both have neglected your relationship and that you believe the "Grass is not greener on the other side, it is greener where it is watered"
