I'm a romantic and say true love. Cause if you have that nothing else really matters, you're happy with that person.
Sure, 200 billion would be REALLY nice, but as for that buying you love... no! if you just want someone who wants to use you for your money, then yeah, you can buy it, but that's not TRUE love. I'm not saying you can't find true love with that much money, but you definitely can't buy love.
