The former The Bold and the Beautiful star, 47, hit the headlines last year (08) when she obtained a restraining order against Corey Cofield amid allegations he beat her daughter with a belt.
Cofield denied the claims and Tylo had the court order dropped months later after reconciling with the guitarist.
The actress split from Cofield for good in May (09) but is only now revealing the reasons behind her decision to boot him out of her family home.
She tells the National Enquirer, "It was like a bad soap opera. I booted Corey out in May after I found a letter he'd left on my computer - a love letter to his old fiancee. He claimed he couldn't contact her because he'd been out of town, but that he missed her."
Tylo is thankful she didn't marry Cofield, her boyfriend of two years, because he has already caused her so much heartache since the break-up.
She adds: "Corey wanted to get engaged in December but I realised he wasn't a marriage candidate for me. ...He screwed up financial things for me. I found bills weren't paid that I thought he'd paid... Since I kicked him out, he's been leaving me alone."
