except one can recognize it in progress ... that little difference is more a life experience thing.
When you love someone, it should just make you ... happy. Not giddy, fireworks (although initial lust can do that), but calm and steady ... trusting. Like your world despite all the crap in it feels right.
And love takes you outside of yourself, because now someone else's needs and happiness matter to you at least as much as your own. That factor is there when you love a spouse, a child, or even a very good friend - their needs and their happiness MATTER to you.
Love doesn't have to be romantic, it just has to have that quality of trusting and caring.
