This incident rang a bell for him. He needs to leave her a way out and essentially himself as well. After having such thoughts, he spent a few days lying there thinking about this. He must provide her a worry-free future. It's not that he's going to be in any trouble, just that he can't afford to rely on her even if there is a one in ten thousand chance. He has to make arrangements for her.
The world is unpredictable, and nobody can accurately predict the future. Just the thought of her being left helpless in case of any harm befalling him made his heart ache.
He used to be careless about think the whole thing through, but now that he is cautious, he is determined to arrange everything properly for her after his demise.
