Oh he definitely was "in love". In fact, if you look back at your relationship, you probably can remember the times when he said those things about you.
The problem that it's a romanticized love. Once the initial thrill wears off and you're left with the stresses of everyday life and when you start to argue with one another, that "romanticized" view quickly fades away.
He's an idiot to think it would always be like that.
