Backstory: MIL has been odd lately to say the least. She first sent nothing to BS (her bio grandson) for his birthday. Then asked DH to come visit alone for thanksgiving (he said no of course not). A few days ago she texts DH to go on his facebook. On his facebook she asks for a school picture of SS. He worked all of those along with some tough tests/appointments for BS who will need surgery. So he in 3 days he had not sent the picture. MIL write BM asking for a picture then writes DH about how if she needs anything to do with SS she will from now on go to BM also that DH needs to learn to communicate with MIL. DH writes back about how she shouldn't be talking to BM (she is crazy) and why she didn't just ask me. As well as, how many times he tired to contact her and she didn't answer or call back. MIL blows about about how sick grandMIL is and how DH doesn't know because he never calls.

Well now MIL keeps commenting on pictures of SS and BS also anything I post. She never wrote DH back when he asked if she had a problem with me. Part of me wants to call her out and be like you can't be like that in private messages then super nice publicly. I just don't know how to handle this.
