Free after four years in the Dochas Centre women's prison in Dublin, the 49-year-old says she will "always care for" her millionaire former lover PJ Howard, but that "I think when you are separated for a long time you start to grow apart.
"It's a natural thing and that's the way things went, no final conversation was ever had."
Over Christmas she returned to the local bar where she met Mr Howard for the first time.
"It was great," she said. "I was welcomed with open arms."
Collins, from Ennis, Co Clare, still hopes some day to prove she was framed for conspiring to kill the property developer and his two sons Robert and Niall. She was found to have solicited Las Vegas poker dealer Essam Eid to carry out the hits.
In the meantime, however, she is in talks with publishers, movie studios and TV companies about selling her story.
In her first interview since her prison stint she reveals her "terror, absolute terror and distress" at being arrested in February 2007.
Coming up to the trial she didn't sleep for months and during the six-week hearing the courtroom was stunned when PJ walked over and planted a kiss on her lips after giving evidence that the allegations against her did not make sense.
She believes he stood by her "because he knew me, he knew how I was with him and I think that only the person you are with really knows you".
She also believes that "someone tried to frame her" and says she has a name in mind.
Initially she became friendly with 'Black Widow' Catherine Nevin, but the two fell out.
"I felt we had nothing in common. I didn't take to her. She wasn't someone I trusted," she said.
At the beginning of her sentence her former lover continued to visit her in prison but "we both agreed the visits couldn't continue because of the media frenzy".
For now she is busy concentrating on a book about her life and the trial and a second book based on her time behind bars.
She is also negotiating a movie deal and several US chat shows are keen to secure her first TV appearance.
