Query: Beverly falls in love?

Dr. Crusher falls in love with an alien diplomat, who is involved in peace talks with an alien planet. But the good Doctor is crushed when she learns that her lover is actually a parasitic life form that lives off host bodies and has lived for years. The episode becomes even worse when the symbiont is planted into Riker's body to resume the peace talks, and when a suitable host comes aboard the Enterprise, the symbiont is finally placed in the body of a woman.
