Que:3. 5 Points to your house at Hogwarts if you could answer any of these questions

Snape did love Lily, through most of his life. He never married. No character is known to have loved Snape. Lily didn't know he loved her because he never told her.

Snape loved lily to pieces throughout most of his life. It's hard to say whether she or anyone else showed any romantic affections towards him, as it is never said or hinted, but I do think Lily loved him as a friend. Finally, No, Snape never married as the only one he loved was Lily, and she married James.

Snape actually loved Lily, but Lily only treated him as an ordinary friend. And no, Snape is not married.
