I immediately thought Sagittarius too. In all I've read about compatibility with Pisces, I've read freedom over and over. The one man of interest fits it.
I'm gonna go with Sagittarius on this one. They are super independent, always on the go, does not like to commit, and won't be held down because they are always exploring something new.
Sagittarius is the carefree unhibited half woman half horse in Astrology. The Sag woman is strong willed and carefree. She to me is the most social carefree creation. This is my store logo now. I love this graphic. I made it but I don't go well with Sagittarius. Sag is too carefree and aggresive for my serious mellow Virgo self lol...

i am a sagitarian-(ophiuchus) and am as "free" as a man can be. http://news.discovery.com/space/your-star-sign-just-got-rumbled.htmlBut check your sign first to make sure you are what you think you are.
My vote goes to Sag, with Aquarius a close 2nd. I'm a Sag and all the Aquarians I know are very transient and independent.
