Being bi-polar myself I feel it is very important that you set boundaries with your son and not walk on eggshells. That is the last thing either of you need I never wanted to get by with outrageous behaviour nor do I want anyone not to be able to confront me and tell me that I am out of line. Maybe you need time and distance and he can learn to appreciate what a blessing he has in a loving and kind family. He has been blessed in this world and should treat you with respect.
