David Cassidy Rejected 'Partridge Family' Co-star's Love ⁠- She Later Ignored Him for 9 Years despite Him Apologizing

David Cassidy and Susan Dey were physically attracted to one another from the moment they met. However, although they remained friends for years, the pair did not act on their feelings until they spent a night together.

David Cassidy was just 19 years old when he got cast to appear in the sitcom "The Patridge Family." On the morning of the day, he learned who would play his mother in the series; David also met actress Susan Dey, who would play his sister, Laurie, in the series.

Susan, 15 years old at the time, was a teenage model who had appeared in "Seventeen" magazine. According to David, she had almost translucent skin and was very beautiful, skinny, and naive.

The teenage actress had never been to California before and was new to filming sitcoms, so she often had to ask for David's help while they filmed the series. The two got along very well because they were physically attracted to one another.

Regardless, David did not act on it because of her sweetness, naivete, and young age. Yet during this time, David's fame from starring in the series had gone over the roof, especially among his female fans.

Girls would hide in his home's air conditioning vent and even throw themselves at him while he rode in his limousine. While visiting London, thousands of young girls came to the Dorchester Hotel where he was staying.

On his next visit to the country, David hired a 200-ton yacht on the Thames accompanied by his security team. But unfortunately, even with these precautions, girls jumped into the river and had to be saved when they sighted him.

Many of these fans were jealous of the relationship between David and Susan, and as one journalist described it, these girls wished he would just appear and take them with him.

Meanwhile, during this time, Susan, who was very sensitive, felt like she was getting overweight due to her background in modeling and how everyone believed a successful actress must have a physique of a British model.

Susan admired Audrey Hepburn and wanted to model herself after the veteran actress. To achieve this goal, she started eating less and subsequently developed anorexia. However, it took a while before Susan realized she was suffering from the disease.

DAVID AND SUSAN'S RELATIONSHIP

After David and Susan met, the pair developed a friendship. They often went on dinner dates while Susan's agent, who would not let the actress get off her sight, watched the two. At the time, the actor also considered Susan too young compared to the girls he dated, whose ages ranged from about nineteen to twenty-six.

Still, David and Susan hung out a lot, and they confided in each other about their families, and the actor even met her family. During this period, David's fame had overshadowed that of his co-stars because his music career had also taken off like wildfire.

Every moment of every day, he was working as hard as he could. As he worked hard, so did his fame grew. The actor could not go anywhere without fans screaming and running after him.

David, Susan, and another co-star Danny Bonaduce once went to Cleaveland to serve as grand marshalls during the city's Thanksgiving Day parade. However, as soon as the parade ended, it turned into an uproar, and about 60-80,000 kids were trying to grab them and even ran after them.

David's relationship with Susan grew during this period, but as close as they had become, nothing romantic happened between them. The sexual tension between them grew once when Susan walked into the room she shared with David and wore just her underwear.

The actress turned off the lights and lay on the bed waiting for David to make his move, but the actor was conflicted.

According to David, Susan lacked the slutty aspect that he loved in females. The actress was just never going to say dirty words to him. He noted: "To me she wasn't dirty. She wasn't nasty. She was good."

David felt trapped because if he had sex with her, he was in trouble; if he did not, she would hate him forever. He also did not want to risk the friendship that they had if he made a move, even though he was tempted. David was conflicted and wondered why Susan had put him in such a tight position.

DAVID FRACTURES HIS RELATIONSHIP WITH SUSAN

Before releasing his memoir "C'Mon, Get Happy," David was concerned he had risked his relationship with Susa Dey. The actor revealed many private details about their relationship in the book, costing him a valued friend.

David was unhappy when he released the memoir and wanted the book to get people in the industry to start talking about him again. His plan succeeded, and after the book's release, the former teen idol got an NBC "Headliners and Legends" profile.

E! News did a documentary about him, and he even got a made-for-TV movie, "The David Cassidy Story," about him. However, most of these publications focused on his past achievements, not his present ones, which annoyed him. In addition, David hated being referred to as a teen or former teen idol.

One thing that the book damaged was his friendship with Susan Dey after he revealed they had spent a night together in the book. For nine years, she refused to talk to David. The actor even wrote her a conciliatory letter but never got a response from the actress.

The actor also disclosed that the pair don't talk anymore and that Susan terminated communications. Even when they saw themselves some months prior, they only exchanged pleasantries briefly. However, David noted he still loved Susan in some unique way.

He stated that he took his friendship with Susan for granted because he knew about her as well as anyone. Although the pair had not communicated for a while, he could never let their relationship go.
