Smoking

So I just found out that my six year olds daughters father smokes with her in the car! Mind you I told him almost two years ago I didn't want him smoking in the car and then putting her in it. Of course he still does it. But for her to tell me that he's doing it with her in the car just absolutely pushes my buttons. We've had a pretty good coparenting relationship for the last year and now I'm pissed off. He wants to smoke with his three other kids in the car. Fine he can do it. But not with my fucking daughter. Anyone who smokes in a car with kids are scum in my eyes. That's just asking for the child to have health problems! Just had to rant. Thanks!
