And... she's blocked
After DH told BM that he would no longer be communicating with her because SD is now 18, BM tried to guilt trip him, and claimed he promised to keep her informed.
DH replied, "I reached out to you more in six months than you did in the previous 17 years. You can't just sit on your ass and expect to get spoon fed everything, you have to reach out and engage. I'm done with this conversation."
And then he blocked her. He gave SD18 a heads up that her mother might be on the war path, but apparently there's nothing.
I didn't mention this yesterday, but guess who BM blames for DH not calling her? ME! Apparently I have some spooky voodoo which renders him incapable of picking up his phone from across the country.
