Eros has always been a player. Everyone knew that. You did too. That's why you hated him so much. He's literally named after the god of love but it didn't even look like he knew what love really was. And he didn't. Until he met you.

He texts and flirts with many people, yes, but he fell for you after you shouted at him about "true love". He normally hates shows of commitment, but he wants everyone to know he wants you, and only you.
