The answer is not entirely clear, but it mostly started when Firestar saved her in the battle with RiverClan, before she fell off the gorge in the second book in the original Warriors series, Fire and Ice. She began to realize that he wasn't such a bad cat after all and started paying more attention to him rather than torturing him with Dustpaw. She soon started to fall in love with him when she realized that they had similar personalities, similar ages, and that he was a very handsome tom.
Firestar
He also loved spottedleaf, but his mate is sandstorm. Cinderpelt loved him but he never knew.
Yes, Firestar is in love with Sandstorm.
That Firestar has stopped loving Spottedleaf in the same way as Sandstorm and he is ready to move on from her.
The warrior cats technically don't "marry" each other. They become mates. But firestar is mates with Sandstorm although he loved Spottedleaf before her. Cinderpelt also liked Firestar.
Well....because she fell in love with him, I guess. But it was a little rocked by Spottedleaf, who died, but Firestar/heart still loved her. But he found out later Spottedleaf didn't mind him loving Sandstorm, and they became mates. I don't know exactly why Sandstorm started loving Firestar, but they love each other very much through the series.
fire star always loved spotted leaf but after she died he fell in love with sand storm. the main answer is he loved both but since he knew sand storm better he loved her
Firestar began to develop feelings for Sandstorm during the course of their adventures together in the original "Warriors" series. Their relationship deepened as they faced various challenges and shared important moments, eventually culminating in them becoming mates.
