She didn't prevent his return. She just didn't want to look for him and I don't blame her. Why should she want to go find the douche that rode off in a pout because Nikki got married? The Newmans have the resources to find him themselves. Sharon couldn't stop them.
I'm waiting for the Newmans to pay for all the things they have done. Sharon pays over and over for everything, even things she didn't actually do. I only wish NE had been destroyed beyond all hope before Victor's sanctimonious hateful ass returned.
