My dad is addicted to meth now?

I am so upset.

Meth is one of the big drugs in my small town but there’s drugs everywhere I guess.

I am 36 weeks pregnant and my dad is 47. In the past couple of months his behavior has been really shady and we found out he was on drugs. We being me, my younger sister (21) and my stepmom. I can’t take this. I know the best thing is to just let go and cut ties. He wasn’t around much when we were kids because he was a truck driver. When we got older he could come around more and I am sad to say my son and daughter (still baking) won’t have a grandpa. I refuse to let my kids be around that type of behavior. It just really upsets me because my mom was very toxic and addicted to alcohol so he doesn’t have a grandma either besides my stepmom. We try to get my stepmom to leave my dad because we don’t want her to get hurt but if she won’t leave him I’m at a loss because I canthave my son around that, they’ve been together over 15 years and I just don’t see her leaving...she is a great grandma to my son (3) and the only family I have left besides my siblings.

My dad has been out all night since 4 pm yesterday with my stepsister who has been addicted to meth for years now. My stepmom finally found them after searching around town well found his car. They still wouldn’t come out this persons house idk if it’s due to embarrassment or they are just so ‘messed’ up from the drugs or what. He has left before but always ended up coming back home after a couple of hours. We are more worried due to the fact that he has had seizures his whole life and has to take medicine daily. His medicine is at home and if he doesn’t want to come home there’s nothing we can really do. We just know how unsafe it can be for both of them especially if he gets in the car and drives. Is it horrible for

Me to say I hope they get caught and go to jail. Maybe that will trigger something in him but probably not because I know addicts will only stop if they are willing..:
