It has been hard for you, although supportive of your mother, after the loss of your father to accept life would never be the same when another man entered your mothers life. This is a new era for your mother which her grandson cannot possibly understand and I do not believe she is as you put it disinterested in her grandson.The only way forward is to speak to your mother, on her own ,and explain her grandson is asking for her, Why not ask both mother and BF for a day if as you say your son has not seen is GM for two months. This will give you some idea how the friendship is progressing ?and your son to have is gran for a day. If this can be a regular invitation and the only way your son is to see his grandmother then this unfortunately has to be the way.
