So she fell in love because of greed. How romantic.
There is no evidence Julie was looking for a rich man to look after her. If she was, then she could do better than 'potential' in 20 years. There are plenty of older men that would be happy to be a sugar daddy to a 20 year old.
I was about to say that we don't know anything about any previous boyfriends but it's just come to me that she was going out with someone -a fellow student- who she dumped after she started going out with Jeremy.
It's very mean of you to suggest that she fell in love because of greed. All I said was that greed doesn't preclude or prevent people from falling in love. As for romance, I imagine we all have different ideas of what constitutes it. You're the one who suggests she could have found an older man. You clearly have made no attempt to understand that Julie may have thought, despite that YOU think she could have done better, that she had found in Jeremy, everything she wanted.
