Drinking problems and pregnancy

I am pregnant with my second baby! We aren't going to find out the gender! 🙈 eek. But before my pregnancies and between the two, my husband and I like to throw parties for our friends and have fun or go out with them...etc...but now it seems like he doesn't even want me to be pregnant he just wants to go out a drink and have fun. And he does he leaves me pregnant working from home, luckily we have a full time Nannie that lives with us to help me with Graer...but what do I do? He wasn't like this with our first baby..
