Obsession - "an idea or thought that continually preoccupies or intrudes on a person's mind." So it's at least confining to the person obsessed and if they are controlling, then it's confining to both people. @SW-User

@SW-User It's nice, isn't it? I haven't heard it for ages but somehow your question reminded me of it. I've got a CD single of it somewhere, I must dig it out. Lol :)

If it's truly love, no. But the typical way people define or think of love....Yes.
