MIL tried calling the last few days. Today I talked to her.
Apparently OM is a gem. Outstanding warrants, early 40s, a 5 years old daughter with a foul mouth and disrespectful, a broken down vehicle that he can't fix, no job, no money.
MIL said W can't handle the kid. She has brought OM to parents house. MIL said no more and he can't stay there.
Her parents cut off supporting her with money. I explained that I'm not giving her money either. She agrees.
She said the newness is wearing off and reality is starting to set in. It's crumbling. Be patient.
Also said she is not herself and acting crazy and out of her mind.
