This happened back in early 17. For some backstory, I found out that the two people I grew up thinking they were my cousins were actually my half siblings. 

For the last two years of his life my brother had been separated from his ex and had moved on to another girl, and they hated each other. Thay have two lovely daughters together. I was spending time with my newly found nieces (known them since birth, just a different title now) and just being an uncle. Brought around our kids so they could really get to know each other and the like.

After my brother's unfortunate death, the ex started posting on FB about how much she missed my brother and making everything about her. Let me remind you, they hated each other, and my brother was in love with the other woman.

She started three or four GoFundMes for what i have no fucking clue. Got a shit ton of money from all the people he worked with, and I have no idea what she did with it. 

One night I posted something on FB that she didn't like, and she deleted me.

This gave me the idea to really ream her a new asshole about the whole way she was handling the situation, so I sent her a choicely worded ~1000 words on why I hated her, and what she can do with the money she stole from people.

She immediately screen shot that and sent it to my mom and sister as if to "tell on me." I am no longer allowed to see my nieces, and have been NC with her since. Wife is still allowed to talk to her and bring our daughters around, but not me.

What say you Reddit, AITA?
