It's great that the mom has "changed" and wants to be a mom after abandoning her child 3 years ago. Even you can admit it would be best for the child. BUT...she can't just swoop in and take him from the only parent he's had! She should be willing to do supervised visitation herself, and increasing parenting time when it's appropriate. If she's not willing to ease herself into the childs life...then she hasn't changed, now has she????
Boy, drugs and bogus GAL's...do I know about these. I've got some horror stories about both of them which, when looking back, make me laugh my behind off! At the time, of course, they weren't funny at all. I was accused of doing "hard core" drugs in front of my son, who wasn't even in my home...and all I was doing was eating a fricken Taco Bell burrito!!!!! DEA came busting through my door while I was at work because monster, who's the damned drug addict, was mad that I was sitting on the same couch as another man! Months after I left him!!!!! (oh, forgot to mention, monster got into my home without permission) I have a GAL report that is so full of lies and deception even a politician would be proud!!! Sheesh...don't get me started!!!!
You've got to get that GAL report scratched from the record....man, this is just wrong. You need to get a new lawyer, no matter what...and then request a continuance while he/she figures this mess out.
