i know the fact..
I want to merge this several simple sentences into one complex sentence in korean.
1. you have a lot of things to say to me / 너가 나한테 할말이 많다.
2. you can't say it (cause it might hurt my feeling) / (나를 아플 수도있을것 같아서) 말할수가없다 (말못하다).
3. i know everything so it's okay / 다 알고 있으니까 괜찮다.
The complex sentence that i want is
"i already know the fact that you have a lot of things you can't say to me so it's okay"
I'm struggling with "the fact" please help me...
