Question

Why should you not call upon a deity of love? Why not cast a spell regarding love as long as you don't harm anyone or interfere in free will?

That's two different questions! You can cast a spell without needing to involve a deity. Remember that deities, even if they were once human, are very different from us and have their own needs and wants. Are you already sincerely devoted to Aphrodite (for example), or did you just pick Her name off a list of gods of love? (The first one will get better results.) Many traditions honor ancestors and spirits of place (like the spirit of a river that flows nearby) as well as deities. Just cast the spell and leave open the possibility of any one of these spirits or powers being the one to answer. If a deity answers, you will know, possibly with a bigger impact or cost than you were prepared for!
