Alexandra, 33, claims her friend, William, 57, is obsessed with her and says he tells people they have been dating on and off for the past eight years — even though she insists she has made it clear she is not interested in him romantically. William says he loves Alexandra and wants to spend the rest of his life with her — but  has he overstepped his boundaries? Is Alexandra sending William mixed signals?

More than Friends?

Former train conductor William says he met Alexandra about eight years ago, when she was a passenger on his train. For him, it was love at first sight. “We started dating pretty much right away,” he says. “I fell for her. I knew right then and there, this is the girl for me. I’m in love with this girl.”

Alexandra insists she has made it clear to William all along that they’re just friends. “William is delusional, because he thinks he is my boyfriend, and he will never be my boyfriend,” she says. She claims William has become obsessed with her and even stalked her. "He would call me 100 times in one day. He would leave me numerous text messages,” she says.

William denies calling Alexandra 100 times a day but admits he wants to spend the rest of his life with her. “I don’t know if I can just be friends,” he says. He also admits he has gotten physically violent with Alexandra in the past out of jealousy. "I'm not in total control sometimes when that happens," he says.

“This has been a nightmare for me.”

Has Alexandra sent William mixed signals?

How does Alexandra explain the photos William keeps in a box — including some that can't be shown on TV?

“Just because you want to be with her doesn’t mean that you’re entitled to be with her.”
