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.

No, a flatworm does not have a body coelom.
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.
Planarians are free-living flatworms, flukes are parasitic flatworms that infect various host animals, and leeches are blood-feeding segmented worms.
Planaria are free-living flatworms with a simple body structure, featuring a distinct head with eye spots and a mouth located on the underside. They have a well-developed nervous system and can regenerate lost body parts. In contrast, tapeworms are parasitic flatworms lacking a digestive system; they absorb nutrients directly through their skin from the host's intestines. Structurally, tapeworms have a segmented body made up of proglottids, which contain reproductive organs, allowing them to reproduce efficiently within their host.
