Sounds horrendous
Let your grandkids know you are there and love them and your door is always open
Step back
I know that is hard but it sounds like you have become the punchbag that’s not fair or right on any level
She is making choices and you are trying to take the blows of the consequences as mums do but she is hurting you deeply and it is obviously but ultimately not helping her or her addiction
A pattern has evolved
Sometimes by not reacting as expected it makes them stop and think
Be strong
You have to start protecting yourself and look at the situation long term
The kids will begin to think what mum does is normal and maybe need removing from the chaos before it’s too late and the pattern repeats or they witness tragedy
it is her decisions that are hurting and distorting everyone
Sometimes you have to be cruel to be kind and do the right thing
Wishing you strength
