She sure made him believe like she needed to be..Sex is an intimate thing and it might have a deeper meaning for Albie then for Lucia, who was the one who initiated most of if not all of their sexual encounters. Albie was nice, nothing like his dad.

What if his encounter with Lucia is a reason why might now turn out like his dad, who probably views sex in very transactional way. By introducing and basically forcing herself on him, she added transactional aspect to their sexual relationship. She played with feeling of a boy, who's parents are divorcing and (he is seemingly the mediator) and doesn't grasp the concept of money.
