Narcassistic mother went too far

This is weird to not post about my psycho in laws.... Guess its my moms turn to bat. There is so much of a BG, but the condensed version is my mom has Undiagnosed narcissistic personality disorder. I'd bet the farm on that since in the text books there is her picture under the criteria, lol. Any way everything she does somehow or another has to do her or how it effects her. The latest drama is she asked me for my SS# so I could sign up under her so they could get credit for their downline for their business. She tried to pass it off as a favor for me, but I am not ignorant. When I told her that it wasn't a good fit. She told me that I'd be responsible for her business going under. Geez... Drama much? Anyway I told her I'd get back to her. You can't talk to her so I sent and email thanking her for thinking of us but it just wasn't going to work for us as this time.... Well, I haven't heard from her. She seemingly cut me off. My mom has a tendency to act exactly like a 3 year old when she doesn't get her way. Oh ladies... I have so many stories, but that is for another time.



So fast forward... My sons 1st birthday was yesterday. Not a call or a card.... Not one little acknowledgement. Really?!! Baby's first birthday and nothing.... Because I didn't sign up under her? I'm pretty pissed off. But do I even say anything or be done and have my own cut off party. She thrives on drama so I'm guessing not saying anything is the best... But it makes me so mad. My brother can stand up to her and put her in her place, but when I do it.... I'm soooo evil. She's so different with me. You know.... She's only came to see the baby once... Maybe she forgot I had him.
