Need help!

I'm 37 weeks and 4 days. My bf and I got into yet another fight. We've been going to counseling for almost 8months (started when I found out I was prego) but nothing seems to help. The main thing I or we fight about is his drinking. I've asked him to stop bc I need his full support if I go into labor. He can get out of control at times. He has twins that are 6 with an ex and I have a 6 year old too. He doesn't drink around them but does around mine. We have my lil girl full time for the most part. I'm just really hurt that he hides his drinking and lies to me about it bc he just won't stop till I have the baby. I don't work he pays for everything so I feel stuck. What do I do?! (Sorry if this post is all over the place I'm still upset)
