How can they forget Ed?!

I don't know why I am surprised but I spent this past evening with my "mother", brother & sister in law, nephew & his girlfriend. I ave been awake now crying since 2am. It was my "mother's" 90th birthday so my brother & I took her out for dinner. I write "mother" in quotes because she has never been anything that resembles a mother to me and I have little to do with her but I felt for her 90th birthday I should make an appearance. Ken didn't go with me, not because he isn't well (although it makes a nice excuse) but because he cannot take how cruel my narcissistic "mother" can be. Tonight, I had to listen to several hours of her stating how lucky we all are that we have "long lives" in our family. Really? well, Eddie, by the way, remember him, your first grandchild? died at 37 from a heart attack!
I don't begrudge her a long life but no one, not her, not my brother, not my nephew, mentioned Ed at all! My "mother" was smiling & happy, thrilled to be the center of attention. I mentioned my son for a moment and got stares! Let's all just forget he existed!!!Well you know what! Screw you all!!
My son was a sweet, kind person who would never intentionally hurt anyone! Its not fair, its not fair, its not fair!!! What kind of a grandmother acts as if her first grandchild never existed!! I will never stop talking about Ed! He lived! He loved! He made a difference & how dare they ignore him!
I told Ken when I got home. Ken was amazed that I was surprised. As he said, "you know how they are." He is right. I do know, but I was still hurt by how little they care about Ed. No calls from ANY of them on Ed's angel date or his birthday! They don't even remember!
That's why I come here. Ed is not forgotten by you. THANK YOU!
