She was there 

Always haunting his mind. The slightest thought of her would cause a mental breakdown. He was afraid of her. He knew what she could do. He knew from the start that she was crazy obsessive, and possessive. He thought it was y and seductive at first. 

But as their relationship progressed he realised it was too late to get out.

She was as rich financially as him. She knew his phone number. Where he lived.

She even started sending letters and packages to him, and his relatives as well.

But now, she was stalking him. Outside his house every night. Sending him annerversary gifts.

She was, The Stalker
