Tamjakr, this is your son, not his, correct? This is something you may want to set a boundary around. Something like; hey H it's not appropriate for you to involve my son in your relationship with OW, especially without my knowledge beforehand.
I guess I am confused about your situation. Is your son living with you? And this is your son, not H's? And you are living at a different location from H?
So why is your son seeing H at all?
