I'm a wreck

So me and hubby is not on good terms I'm currently 9 wks pregnant and nauseous all the time he is stressing me about cleaning I have 2 toddlers so I'm constantly picking up after them and cooking 3 meals a day we have a huge house I understand when he comes home from work he wants a clean house but until I hit my second trimester I'm doing what I can when I can I think that he think I'm using my pregnancy as an excuse to be lazy he wanted this baby just as much as i did we tried for 1yr and he is going to the bar more when I tell him I feel like have days for ur friends but we need days with u as well work all day then go to bar instead of coming home to your family is hurting not only me because of the emotional support but the kids need their father here not out getting into trouble I'm not even speaking to him right now or sleeping in the same bed tonight because the alcohol on his breath I'm not even going to confront him because when I do we argue for hours and I'm just not going there I just don't know is he being selfish or am pushing him away we worked so hard for ours and would hate to see it go down drain** please help me if u have any suggestions what to do to save my marriage**.Thanks
