Speak for yourself.
"Unconditional love" is one of those absolutes that just doesn't exist. In your own example, you thought you loved somebody "unconditionally" but it turned out to be temporarily. The condition was, "until you screw up beyond Point X."
The best you can do is come as close to absolutely unconditional as you can. Be aware of the conditions you package with your love.
