Okay, the phase thing is true. They will play between the two of you for years. What bothers me is daddy's lack of concern for your feelings toward his parents enjoyment on this. You are his full family now, and he needs to be supportive. If that means he has to talk to them about it, so be it. If he refuses, you need to say something or stop going all together. Something has to give, and it sounds like you already have been. Good luck!!
