Sorry, I didn't understand that you once lived with your grandparents. I'd advise you to go talk to your grandparents and see if they agree with you moving back. If so, then you need to look into the legal term of "Emancipation of a youth", You would have to go to court and this would give you the rights you are looking for. (As to making the choice of moveing back to your grandparents home) So after you talk to your dad and stepmom and if that doesn't sove this situation..then talk with your grandparents re:this Emancipation. (I'm not an attorney, but I had a young client who was in a divorced family life and did this..so that she could go live with her father, since her mother wouldn't allow it) Good luck and I hope the puppy is doing well!
Shasta, the first thing I would do, other than try and talk to the supposed adults involved, is get an x-pen or use redford's suggestion. The dog is still better off away from your step mom, no matter how you cut it, and you'll be home after school to spoil her. I would definitely look into moving back with your grandparents,it does'nt sound like your stepmother really wants the responsibilities that come along with a man with children.
I would love to move back with them and would do anything to but my dad would NOT let me go wihtout a fight so i dont think that would work. I mean, i love my dad. Sure he can be a *BEEP* but i love him and i dont want to do anything to hurt him. He thinks the situation i am in is a good, happy, and stable one and of anyone says different he gets really hurt and i dont want to be the bad guy. I know it would be the best thing for Shasta, and me, but i think i just need to have a talk with them and see how that goes THEN decide weather or not further action, emancipation, is needed. So thank you all very much for your advice and i will get back to you when i know more myself!
