If he has been drinking tell the kids to NOT get into the car with him and to call you IMMEDIATELY to pick them up. I went thru. this last year with my kiddos tho. I'm not separated from my AH. I stopped allowing them to ride with him. Since your situation is a little different tell them not to ride with him if he's been drinking and to call you. You might want to call a lawyer too and see what options you have. I know more great advice will be coming your way...hugs...that is so scary for you and the kids.
