Need some advice please

Hubby and I been fighting lately stressed out due to bills moving ect.. last Friday he stood out late then Sunday ditched my son and I. He apologized we made up but today I feel like he's going MIA again. He hasn't called me he said he was going to get out of work 3-4 but he isn't home so I'm guessing he's with the guys again. There's no communication I really hate this idk what to do. I really do love him we been together for 8 years but I feel like I'm starting to have enough I know everyone goes through bad times but I can't stand it+I'm 13 weeks pregnant
