If you know your pushing, then tell him you know that and can't help it. If you know your " reading too much into it" hen tell him . Has he given you a reason to not trust him? If his passed was speckled with drugs and poor choices perhaps his parents are afraid to get close to you for fear he will fall off the wagon at any moment and you'll be gone. I know my family in laws were afraid to accept me as a protection to themselves in the event I was temporary. Being I had my own issues I " took it wrong". Wishing you well.
