We all know various manifestations of love. I came across couple of interpretations by Linda Goodman on love shown by various signs in her book.
1. Aries - When he/she allows you to select the movie you both going to
2. Taurus - When he/she speaks more than usual
3. Gemini - When he/she remembers things about you
4. Cancer - When he/she buys you a lavish gift
5. Leo - When he/she skips a gathering of friends to be with only you
6. Virgo - When he/she looks lovingly at your messy closet
7. Libra - When he/she takes your side
8. Scorpio - When he/she helps you get a voice
9. Sagittarius - When he/she saves little stuff of you
10. Capricorn - When he/she takes you to meet their family
11. Aquarius - When he/she keeps coming back
12. Pisces - When he/she takes you as their saviour
