BRUCE JENNER Sons HAPPY With Separation

Brody and Brandon Jenner became estranged from their dad when he married Kris in 1991.  They were raised by their mom, Linda Thompson and David Foster, who married Linda after she divorced Bruce.  We're told the boys were devastated, and believed their real dad abandoned them.

Bruce Jenner's 2 boys blame Kris Jenner for robbing them of their father and they are more than happy over the split sources connected to the family tell TMZ.

We're told Brody and Brandon know their father Bruce didn't pay child support for 10 years, and after that only $1,500 a month. Again, they believe Kris was pulling the strings.

So now Bruce is living in Malibu, close to Brody and Brandon, and they are reconnecting with Bruce in what we're told is "an adult relationship."
