SJ0102 you clearly have a lot of growing up to do and learning about relationships as well as tact and love.
Family is not all about one person being the 'kingpin' or in your case being the new 'queenpin'. It is about being a complete family unit which obviously includes all the members. Excluding someone is corrosive and poisons everyone involved - ie the whole family. The funny thing about love is that the more we share the more there is and the more there is then there is more we can share.
I do wonder about your relationship with your own mother as you don't mention her. Do you have siblings and if so what is your relationship with them? Your post is all about you so let us look into the future and see what will happen when your baby boy has grown up, possibly without a paternal grandmother, and he marries a girl who adores him but she is not keen on her husband's controlling mother (as that is how you come across). Your son will have learned the lesson from you that paternal grandmothers can be excluded so he will think nothing of it when his wife, your DIL, decides that you are entirely disposable. Now think about your feelings in that situation because it is entirely possible and going by your post is even predictable.
