Correcting the Ex???

I may not be right about this, but Ex and I had agreed that the Birthday parties were for the kids and that was their special day. Then she calls to un-invite me because her family thinks its inappropriate that I be there. I started to get a little mad today and sent her an email.

The more I think about it, the more irritated I get that I am the one being excluded from my own son's birthday at the demand of your family.
He is MY child, not theirs. Their "discomfort" at the situation is their problem, not mine.
This is not your Mom's birthday, or a baby shower for [cousin], or a graduation for [niece]. This is MY boy's first birthday.

It is EXTREMELY inappropriate that they even suggest that his father be absent. It is FUCKED UP as a matter of fact. I do not care to interact with them any more than they want to with me, but this is an event for my child.

I have no choice but to take this as I am now no longer allowed to go to ANYTHING that they may be part of...sports games, recitals, plays, graduations....How about their weddings??? dear old dad is not allowed to be there because Mommy's family is "uncomfortable". He of course needs to contribute money, but attendance is not allowed??

Fuck this..I'm pissed off. This is the most ridiculous thing I have ever heard. If you don't stand up for what is right on this one....i can't say that I will be able to speak to anymore. I can't believe this.

If you actually let this happen, I will sever all ties and contact with your family. This will include your mom. I will not interact with her in any way...as requested. This includes picking them up at her house. If they are with her, that is where they will stay.

You need to to stand up for this one... You need to. We don't do "family holidays"...This is my kid's birthday party... Who gets to explain to [daughter] why I can't go to her birthday parties anymore??? How about her kindergarten graduation?

You need to fix this....

Now that I read it again, it sounds a little harsher than I intended but I was getting mad about it. I know I got my point across at least. I didn't say that I was sick of her family making decisions for me. They had done that for ten years..
I also didn't bring up that she has told them the divorce was my fault and that she was a perfect angel and I am a horrible monster.
I have not asked her to tell them, but that's what she wants them to believe and I bet that's where this is stemming from.

I don't know if what I did was right, but it sure feels like I am fighting to right a wrong here. I would understand if I was still acting like a jackass towards her....but no...I'm going to fight this one to the end too. At least this fight is only for a week.
