Whom Did Allan Love?

When the Titanic sank in the ocean, four gentlemen and four young ladies floated on to an island. After a while, all of them fell in love with each other. Each person loved one and only one.

The girl that John loved fell in love with Jim. The girl that Allan loved fell in love with Bill. The gentleman that Rose loved fell in love with Mary. Gloria loved the gentleman who loved rose. Gloria did not like Jim and John. Bill did not like Mary. Jill did not like the gentleman who loved her.

The question is: Whom did Allan love?
