Bro left ex SIL when newphew was 4. She was doing drugs and cheating
Since then she has
Filed a false RO against bro (dismissed)
Got bro arrested in front of newphew after she attacked him
Bit my bro
Told newphew to his face he was only worth her state benefits
Made newphew responsible for her
Disappeared for months at a time
Made newphew walk home day after he was almost adbucted
"Forgot" to pick newphew up from school more times then I can count
Would keep newphew home to watch her younger child
Wouldn't have him change clothes, shower or brush his teeth the 4 days a week she had him
Ditched him on Christmas last year
This list is long... And it is only the things I have personally seen
Now... Newphew just turned 14. He no longer believes moms lies. He wants to stay with dad (and he does, hasn't seen his mom in 8 months)
Newphew has all As and Bs for the first time ever
His SM and him have a solid relationship for the first time ever

Funny thing, my bro has never been a Disney dad... But at times a guilty dad. Guilt for newphew being stuck with his BM. I'll be teasing newphew and bro will pipe up with we are not making fun of newphew we are being supportive. For the first time in his life, newphew responded with dad, this is how Aunt is supportive and shows she loves me. She isn't being mean. I was floored!!!!! Where is my whining, clingy, insecure newphew?!?!?!?! He has come so far. And I'm soo proud to be his Aunt. He is showing he can do and be just who I thought he always could!!!!!
His BM... If I ever see her again she is not going to have a good day. Last time I saw her, she lied to bro and blamed newphew. Bro errored on the side of newphew lies. Great parent move... But BM is the queen of lies. I called her back and she straight out told me she lied to bro. I made her meet me at the store and fix the issue. She has always been a. Little scared of me. In front of newphew she stated I didn't want your bro mad at me, he loves his son to it's ok if he gets mad at him. Newphew was standing right next to me.
