consistent or everchanging...

Tomorrow is the day...the last day before the end of this period..then summer..then Denmark,,,then who knows what.. I find it a bit comforting that nothing in my world is consistent and everlasting..but I also find it frightening..howcome love is consistens when nothing else is? Is that a reason to question if it's really love? Or is it a sign that love is greater than all other things?
Now is the time to say that I am hoping for the latter option? BUt I have to be honest to myself and say that I am not sure about the meaning of love...
I mean, I can feel it, I can show it through my actions, I can tell my baby how I feel..and I can mean it from the bottom of my heart..I can feel the pain of separation..and I can feel the earging and longing for the moment when we meet again..but still, somehow, I am not sure..
What love really is...any suggetsions?
