I don't think anyone can quite explain this connection in its entirety to give it justice. Again labels are labels and every "tf" connection is different for every one of us but the common factor is this pure undying love, Godly and it is a part of heaven, so there has to be something on the soul level taking place much deeper than a regular soul mate connection. We have lots of those connections like bf, child, mother so on, thus this "tf" is very intense and deeply spiritual.
