Maternity leave money drama

My hormones are making it super hard for me to communicate with my husband RATIONALLY.

I'm the bread winner in our household making about double what my husband does but he actually spends our money on himself 100 fold what I do. For instance, for February alone, he's hit almost $300 in fast food, liquor store, and bar trips. Where as I have a charge for $3.42 for a caribou coffee.

So here's my dilemma. I don't get paid maternity leave. I get 6 weeks unpaid but have 4 weeks of vacation I can use. I can throw it on the back end on my 6 weeks OR use it during so that we only have 2 weeks where I don't get paid.

I wanted to meet in the middle and do 8 weeks leave and use up my vacation time but my husband says we can't afford it. I don't have a single clue how to approach the situation without crying. I don't think it's fair that I have to go back to work so soon just so his lifestyle won't change. I love being able to give my husband a life he loves, but I don't know how much longer I can neglect my wants as to supply him with his. I'm usually good at taking a step back and giving myself advice that I would give a friend but right now, almost 36 weeks pregnant, my hormones won't allow me to do anything but cry when I try to talk to him about it.
