As with in business , you say things straight from your heart , even though I know your past more than most , what is done is past and it is more than enough time to move on .
Let the grand parents spend more time with your son and maybe it will give you more time to concentrate on yourself and your future , otherwise he might get you upset and if he is naughty he can upset the grand parents instead of you , ha ha , as I know how much time you spend on his homework with him .
A lot of kids both male and female can be a pain as they move towards being a teenager especially when they can play 2 sides off if they get told no from 1 side , they even in the same house will ask often the other parent in the hope of a yes , so just set out some basic rules and take it from there , god bless .
