There are a lot of desperate and lonely people (regardless of gender) out there. When you are writing a person in prison, and starting a fake ass relationship with them, the writing is on the wall. I don't know whether to laugh my ass off or feel sorry for those people when I've seen the many stories about that over the years.
Hell, I think one of the Menendez brothers even married a Playboy playmate while in prison. I did laugh about that one while thinking you married a prison pen pal you stupid bitch because you thought you would get money gold digger? That's not how it works dummy because he doesn't have access to shit now other than 3 hots and a cot for the rest of his life.
