What zodiac sign is more likely to dwell on past relationships?

And still be in love with their high school sweetheart?What zodiac sign is more likely to dwell on past relationships?
Scorpio, Capricorn, Libra, Aries, Taurus.

Water element signs arent the only signs capable of dwelling on past lovers.
I hate to admit this because it's not "normal" for me to dwell over past relationships but I do over my first love. I'm a Sagittarius and I usually don't care about anyone I dated before but my first true love is one that I never seem to get over no matter how many years go by. :X It's odd because I have a venus in Sagittarius and almost no water signs in my chart. I'm thinking it's more of a psychological thing rather than astrological though.What zodiac sign is more likely to dwell on past relationships?
Cancer fall in love very easily but also takes more time to forget about a loved one.

They are the most emotional/sensitive of the zodiac so it makes sense.
Water signs. They are soooo emotional. It takes along time to get over it and start over. Everybody always has a soft spot for the high school sweetheart. Life was way less complicated.What zodiac sign is more likely to dwell on past relationships?
