Need to choose better. I don't see how she could have seen any other outcome.
Only people I feel sorry for is her children.
God be with them and protect them.
Someone should take the kids away from that toxic environment, including the mother, she clearly isn't capable of making good decisions. Just emotional impulse.
Hopefully her parents or she has black grandparents at the least capable of taking care of them, otherwise it might be a wrap for those kids.
TLDR; Get those kids to a safe place, everyone else involved is retarded and share blame.
