Ok, why do we have romance really? We love it, we adore it, we are all crazy about it. But WHY do we have it?
I think it is the deep need to find someone that you really connect with. If we are connected with spirit before our tour here in earth, that connectedness must be something we already have experienced in another state.
Then we truly long for that feeling of being connected. But the only way we do it here on earth is by truly loving someone.
So we trod along, looking searching for what we have already lost. When we find that love, it is difficult, because we always long for the ultimate connection. But life is hard, sometimes it throws a curveball at you.
But KNOWING that that connection is possible makes us stay in a relationship.
G-d bless the will to be realistic about the scarceness of true mates.
