Well, that depends.
How long into the relationship she gets me that new game system or the new Madden?
How long into the relationship does she expose the inner freak?
How long into the relationship is it made obvious that her LOYALTY to me is unwavering?
How long into the relationship does she start doing these things for me?
Really, the only thing she could get paid for off the rip is probably the first few dates/meals. At a certain point, I'm going to start expecting reciprocation as the end game is to cultivate and maintain an effective and enduring partnership, emphasis on partnership.
Besides, I don't place much value in material things, such as having the best car or the newest phone, etc. so it would be hard for me to justify coughing it up for somebody else.
