Parasitic flatworms have to have a host. A free-living one doesn't.
Yes, flatworms themselves are parasitic. Their eggs, however, can exist for long periods outside any host.
Nematodes have a pseudocoelom (a body cavity that is not completely lined by mesoderm), whereas flatworms have an acoelomate body plan (lack a body cavity). This means that nematodes have a body cavity, while flatworms do not have a true body cavity.

Flatworms
No, a flatworm does not have a body coelom.
Planarians are free-living flatworms, flukes are parasitic flatworms that infect various host animals, and leeches are blood-feeding segmented worms.
Flatworms are the simplest of the worm groups. There are about 20,000 species in this group. They are found many places and can be free living or parasitic. A parasite lives off of another living thing called a host and can be harmful. One of the best known flatworms is the tapeworm. The tapeworm can get into a person's digestive tract and grow to enormous lengths. The tapeworm then eats off the host and is dangerous to the host as it grows and consumes more of the host and its food. Flatworms are found in marine and fresh water.
Flatworms, such as tapeworms and planarians, are examples of acoelomate animals. These animals lack a true body cavity called a coelom and have a solid body structure instead.
