what love isn't.

I seriously, seriously don't know what to think anymore. Is love just a false concept that was developed by hmans because it is human nature to long for something and to want more?? Do we keep talking about love because we know, in our human nature, that it can never be achieved?? Are humans really fit to love? Can one human TRULY love another in the way GOD had intended? Can one human TRULY love another, willingly swallow all pride, comfort in settling, no longer longing for anything "new", sacrifice self-happiness when necessary, I mean TRULY, UNCONDITIONALLY, and SELFLESSLY....LOVE? because i'm beginning to think that love may be too pure for us humans. I'm beginning to think that love may be to good for s. I'm beginning too think that love was only meant for angels, or any creature without human flew.
