titi branch,*Miko Branch, co-owner of Miss Jessie‘s and sister of Titi Branch, blames boyfriend Anthony Spadafora for her sister’s downward spiral and suicide.

Authorities said Titi fell into a depression so bad that she decided to hang herself in her Midtown apartment three weeks before Christmas on Dec. 4.

Since her death, her sister and boyfriend have been in a nasty court case battle and are blasting each other as the source for Titi’s depression and suicide.

“My sister’s death has been a devastating blow,” she told The New York Post. “It was only after Titi’s death that we learned more about what she’d been going through and how her affairs were being managed.”

Miko claimed Spadafora kept Titi from her family, controlled and manipulated her, and used her for money — receiving thousands from her.

Miko added Titi removed her as the beneficiary of her $2 million life-insurance policies; she was replaced with Spadafora.

“It was a real love . . . I was dedicated to her; she was dedicated to me,” Spadafora told The Post. “I don’t want to see this turn into a war.”
