I've gone out on two dozen dates, all $100 or less. Was told by four that we take things up to the next level for $500 to $800 for each date. Only trusted and picked one of the four, and saw her once a month for a year. She was exactly the dream woman (18 years old, which is over 30 years younger than me, and gorgeous) I have always wanted, so -- even though it was expensive and took a lot of dates -- it was worth it. I broke it off after we had tried and done everything I wanted to do. As neither of us wanted any emotional commitment, there was really no further we could take the relationship.
Update after over six years, I've come to the absolute rule to never date actresses. They are extremely narcissistic and unreliable. And they will only respond to assistance with their careers or unrealistic monetary expectations.
