As HollywoodLife.com first told you, Maria Shriver and Arnold Schwarzenegger are in the process of reconciling their marriage — and are even prepared to enlist professional help

Even though Arnold Schwarzenegger had a multiple decade-long affair with his housekeeper, Mildred Baena, his estranged wife, Maria Shriver, loves the former California governor enough to reconcile — but an insider close to the couple tells HollywoodLife.com it’s going to take some mediation from an outside source.

“Maria and Arnold are totally on board to go to marriage counseling,” the source says of the 64-year-old actor-turned-politician and his wife. “In fact, they may have even started the process.”

So why would Maria, 56, forgive Arnold for what he did to her and her family?

“They have been through so much together and even after everything, she still loves him,” our insider explains. ”Plus, Arnold would like nothing more then to save the marriage and has worked with Maria to make things better.”

As we told you last week, Arnold and Maria’s kids have also had much to do with their reconciliation.

Katherine Schwarzenegger tweeted about her family reuniting for the holidays. “Merry merry Christmas everyone!! So thankful for my family an friends and being able to spend the whole day with them! Feeling blessed,” Katherine tweeted on Twitter Dec. 25.
