Love

Okay, so this was really interesting to me. I decided to look up the definition of love, and this is what I found on dictionary.com:

–noun
1. a profoundly tender, passionate affection for another person.
2. a feeling of warm personal attachment or deep affection, as for a parent, child, or friend.
3. sexual passion or desire.
4. a person toward whom love is felt; beloved person; sweetheart.
5. (used in direct address as a term of endearment, affection, or the like): Would you like to see a movie, love?
6. a love affair; an intensely amorous incident; amour.
7. sexual intercourse; copulation.
8. (initial capital letter) a personification of sexual affection, as Eros or Cupid.
9. affectionate concern for the well-being of others: the love of one's neighbor.
10. strong predilection, enthusiasm, or liking for anything: her love of books.
11. the object or thing so liked: The theater was her great love.
12. the benevolent affection of God for His creatures, or the reverent affection due from them to God.
13. Chiefly Tennis. a score of zero; nothing.
14. a word formerly used in communications to represent the letter L.
–verb (used with object)
15. to have love or affection for: All her pupils love her.
16. to have a profoundly tender, passionate affection for (another person).
17. to have a strong liking for; take great pleasure in: to love music.
18. to need or require; benefit greatly from: Plants love sunlight.
19. to embrace and kiss (someone), as a lover.
20. to have sexual intercourse with.

Now granted, these are all pretty good definitions. But how can you define something that is basically...indefinable? I think there's so much more to love than just affection or a 'warm feeling'. Love is sacrificing. Giving of yourself to another person. It's more than just a feeling. It's a choice. You may have affection for someone, but love is a whole different level of affection. Love isn't just romance either. You can truly love your friends just like you can truly love your spouse. It's just different versions of a love that is whole and complete. You honestly can't define it. It's like trying to make a plant talk to you.

On another note, I am getting frustrated with people talking crap about other people behind their backs. How can I trust friends if they aren't loyal to others?

Maybe I'm overthinking this.
