Hi FMpro. Actually I think it is sad that you are doubting your moms ability to be your mom again. Well, she has always been your mom, and I see no reason why you should feel differently toward her.
Everyone makes mistakes, some people make bigger mistakes and sometimes jail or prison is a punishment.
If your mom has always been a good mom then I doubt that will change.
I think many times dads can do no wrong, and moms are expected to be perfect and never make mistakes.
There is no reason for things to change between you, just go on like you always have!!!
