Singlish mommy/pregnant Support groups

I’m 8 months pregnant and this has not been a great first time pregnancy experience. My baby’s father has not been quite the support system I need, well he’s drunk or gone most of the time. And I feel lost and I’m confused and like we argue and I feel like I want to be there then I’m around and i just want to be home. I feel like he’s always talking to girls. He loves attention. He’s a trainer and I feel he’s overly friendly with his students especially when people show me their “training videos” or comments to each other.... I just idk need some comfort or friends or something..
