Fans are wondering what happens next to the love story of Abby and Chad, which got cut short when Chad was brainwashed to dump Abby for Belle. Abby learned that ex-fiance, Ben, isn’t the father of her newborn son after bringing Thomas to the hospital following a health scare. Due to the seriousness of Thomas’ condition, a DNA work up was required from both of his parents. It was during the DNA scanning when it was revealed that Ben isn’t the father of Thomas.

As the story of Abby and Chad develops, Mansi will be leaving her popular role in “DOOL,” as reported by We Love Soaps. There have been speculations that she will exit the show, which she joined in March 2011. We Love Soaps cited Serial Scoop’s Michael Goldberg as its source, which said that Mansi can be seen in “DOOL” until May this year.
