head games

So my daughter in law is playing her old games again.  Or maybe she never stopped.  I don't know why I never realized this before, but she must feel really threatened by me.  Why, I have no clue.  I was never the type of woman who didn't want my little boys to get married, or that no woman was good enough for them.  Not at all!  I looked forward to having daughters in law!  But apparently she won't let my son talk to me, and he is brainwashed enough by her to obey her.  My grandson was born Wednesday night, and my son has yet to say one word to me.  He has texted both my older son, and my husband, but not me.  I have texted him several times, and I only get silence.  But my DIL, on the other hand, is blowing my phone up, just like we were long lost friends.  She even asked me for a picture of ES when he was born, so they could compare it to the new baby.  I thought this was odd, since right after their first baby was born, they took his old baby pictures then, but whatever.  So I did as she requested, but I sent the picture to my SON, not her.  And of course I got stone cold silence.  It is like she is the filter, and everything must go through her, and he isn't allowed to speak to me.  A few weeks ago she messaged me that it was such a shame my son no longer communicated with me, so she would have to cook all his favorite dishes, and not his mother, so could I send her his favorite recipes?  How cruel!  And then she would be all chatty again, and even send me pictures of the food she made him!  What sort of cruel head game is this?  And why?  I have been respectful and polite to her.  I am so sick and tired of her games.  I am not trying to insinuate myself between her and my son, if only she would realize that.  I just want to talk to my son!  And also, today my youngest son goes back to college and that is making me sad, too.  This is just a bad day I guess.
