A woman who was in a long-term relationship with the sicko South Carolina serial killer said he was a good boyfriend who treated her like she was the center of his universe — but now claims she always suspected something wasn’t right with him.

“He gave me a lot of attention and made me feel like I was important,” Holly Eudy told Inside Edition.

Eudy said she dated real estate broker-turned-murderer Todd Kohlhepp for ten years and was unaware of his double life.

“I knew there was something about him, but I couldn’t put my finger on it,” she said.

She told the outlet she now wonders whether she could have been her ex’s next victim but did not reveal why.

Kohlhepp is serving seven consecutive life sentences after admitting to murdering seven people. He was nabbed last November when a woman, Kala Brown, was found chained by the neck in a storage container on his property.

She told police the cold-blooded killer had slain her boyfriend and that there were additional bodies buried on the property.

The killer had previously served a 14 year sentence for kidnapping and raping a 14-year-old girl in 1986.
