Should I just leave?

My second miscarriage this year was on July 26th. Should have been 11 weeks but baby died at 8. My husband was so supportive for the first two weeks. Then just snapped. Telling me I should be over it. That me quitting my job (I got ceptic and was really sick) was a inconvenience to us financially. As if i didn’t know already. Lately though all he wants to do is go out i with his friends drinking. Picks fights for no reason. Pawns things to make sure he has money to go out. Called into his job so he could go out with his friends. I just feel like he’s become so immature. Went from a military man to a low life loser. In college or not we have bills to pay. I feel he doesn’t love me anymore and I’m holding onto nothing. I 100% love him but I think it’s time for me to move on. What do you think. Stay and keep trying on my marriage or leave and don’t look back?
