Kristen Stewart and Robert Pattinson ‘Have a Tough Couple of Months Ahead,’ Says Matchmaker Siggy Flicker (EXCLUSIVE)

On Wednesday, Kristen Stewart shocked the world when she admitted to engaging in a fling with her married Snow White and the Huntsman director Rupert Sanders.

The 22-year-old actress confirmed infidelity reports in an emotional statement to PEOPLE, in which she profusely apologized to her Twilight beau Robert Pattinson, 26.

Will Pattinson be able to forgive her? Or is a breakup on the horizon? Relationship expert Siggy Flicker weighs in.

“Kristen and Rob are going to have a tough couple of weeks ahead of them, if they make it that long. She got caught up in some stupid moment, and I believe that she is regretful and sorry — but the ball is now in Rob’s court,” the Why Am I Still Single? star told Celebuzz.

“All eyes are going to be on Rob to see whether he is going to walk or stay with her. Both are very young, and I believe that if Rob can get over the pain and embarrassment and is able to trust her again, then they can survive as a couple. If he can’t, then the relationship is over.”

After news of the tryst spread like wildfire on the web, Us Weekly printed incriminating photos of Stewart, 22, and Sanders, 41, cozying up in a car in what looks to be a romantic moment.

“Kristen is absolutely devastated,” a source told Us. “It was a mistake and a complete lapse in judgment.”

According to Us Weekly, which splashed its cover with the blazing headline “Kristen Cheats on Rob!”, it was a photographer who caught Stewart in Sander’s car on July 17.

“Kristen was sitting with her back against the driver’s-side window and this guy was kissing her entire body,” the unnamed paparazzo said.

The British director is married to actress-model Liberty Ross, with whom he has two young children, Skyla, 7, and Sonny 5. The couple have been together since Ross was 18 but married recently.

By Wednesday afternoon, both Stewart and Sanders issued apologies.

“I’m deeply sorry for the hurt and embarrassment I’ve caused to those close to me and everyone this has affected,” Stewart said in a statement to People. “This momentary indiscretion has jeopardized the most important thing in my life, the person I love and respect the most, Rob. I love him, I love him, I’m so sorry.”

Sanders told PEOPLE he was “utterly distraught about the pain I have caused my family.”

“My beautiful wife and heavenly children are all I have in this world,” he said. “I love them with all my heart. I am praying that we can get through this together.”

Flicker, meanwhile, says Pattinson and Stewart can pull through — if they truly love one another.

“Having fame, money and status does not protect or guarantee that your relationship is not going to endure struggles. Both have to work at it,” the love expert said.

“There are many reasons to what might have caused her to stray. In my opinion, she is 22 and very young. She may not want or be ready to settle down. At this young age, Kristen and Rob are just learning about themselves, their needs and wants.

“The ones who make it and get back on the right road together are the ones who really want it bad enough. One can never take a relationship for granted. It is constant work and dedication.”
