Gambling Problem

My husband and I used to go out for date night to the casinos. Spend a few hundred and wouldn't mind if we won or lost. I found out I'm pregnant about 10 weeks ago and refuse to go (germs, secondhand smoke etc.)

I told him he can go just don't take your card and have money before hand (he will spend more without me being there)

The past few saturdays, he woken up really early (like 6am) and drove up to the casinos and tells me hell be home by 10am.

That hasn't happened once. We missed our nephews soccer game a couple times (which is embarrassing since we promised to go multiple times) at noon time and he leaves me home by myself (I work from home and we only have one reliable car) and comes home talking about how he won some but ended up spending it all.....

I've voiced my concerns about this affecting our relationship and our baby on the way and he says hell stop once the baby comes but I dont trust it. I believe he is developing an addiction. Or hes addicted already. Idk what to do...
