He's simply not ready and not willing to be forced (tamed) to marry her, as it was imposed on him. You could also say, he loves the thrill of the 'chase' (as a womanizer) and being chased by a girl goes against his code. You see, right from the start, Aturu is at odds with Lum. And so his love would take time to grow as he learns of her value and loyaity.
