Arnold Schwarzenegger still supporting mistress?

It's a no-brainer that ARNOLD SCHWARZENEGGER is still supporting mistress Mildred "Patty" Baena and their child financially. 

But Arnold could have been an unfeeling A-hole and cut her off emotionally.  And after what he did to his wife, it wouldn't be that shocking.

But sources say he still has Patty's back . . . quote, "Arnold has been very supportive of Mildred throughout all of this.

"The scandal going public has really taken a toll on Mildred, so Arnold encourages her not to listen to what people are saying about her and just tells her to stay strong.

 Arnold was photographed driving in Venice Beach on Sunday . . . on a street called MILDRED AVENUE.
