Recently, i discovered that my dad has a child with a china woman outside. I felt so angry but i couldnot do anything.
My dad is about 57 years old with a new born baby child! That could be even be his grandson. We are aware that my dad has been flirting around outside and my mom has been so good too him. Take caring of 3 children, we are now all grown ups and discovered this.

I couldnot tell my mom about this, but at the moment I am not sure what will be the consequence if my mom found out.
And my mom even tried to kill herself many years ago after she discovered that my dad had an affair.

Feel so helpless and I could only keep this secret and wait for the it to be revealed by itself one day. What i really worried is my mom.
What should/can i do? Do you guys think I should confront with my dad?
