Why do you think some women fall in love or date a man in prison?

A discussion got started at work about women who send letters and money to a guy the claim to “love” in prison…even death row. I’m not talking about trying to keep a relationship going before the guy went to prison, they’re actually starting a relationship and make plans for a life together once the man is released. What are these women thinking? Do they even care about the fact that their safety could be at risk or that they’re just being used for their money and generosity?
