What to do? :(

I am from Europe and met my husband 4 years ago, got married fast and we have been married for 2 years! I am 31 he is 37! Back home I graduated college and I have also a Master's Degree! Came to USA, in the beginning it was hard, I had a student visa and worked as a waitress! That's how I met my husband! He is a bartender! He was in school when I met him but he didn't finish it! Because I had to wait for my green card I couldn't work for over a year, then I went back to waiting tables because we needed money! We traveled and we worked in many places in the Country! He said so many times that he will go back to school! Then he changed his mind and he said he wants a career with Caterpillar (a diesel program)! I supported him with that too! I am pregnant now (6 weeks) and we were talking about the future! He mentioned in the past going back to school  (the previous school) or going to the diesel program! Now he said he doesn't want to do none of those! 

He is not making money as a bartender where we are now! Plus, bartenders have a horrible life and schedule, come home at night and I would get a job in my field and work during the day! Besides that, he had drinking problems and working in a bar it is not helping! Especially since he is working hard in not drinking! 

I love my husband to death and he is an amazing man, but when it comes to work I think he wants to choose the easy way! It's driving me crazy that he can do so many things and he is NOT! His previous school program was in fine art, and I supported him even though I know how hard it's to make a living selling pottery! We are struggling financially and today he said he wants to go take some classes (when we barely have money)! I said I don't think it's a good time NOW because we have a baby on the way and we need to save money AND move again very soon!

It is our day off, he got angry, we had a fight about Both the bartending and the fact that he wants to spend money on something that he doesn't need now or doesn't consider in having a career with (the pottery)

He is not excited about the baby, this is our second one, we lost our first in October! 

I am being a good wife and I gave up all my dreams and my family to be with him, but he is not taking serious anything, the future, the baby, nothing! 

I needed to vent and cry about it! I need an advise! Thank you!
