I have no one and I’m hurting

I’m 3 weeks away from my scheduled csection with a baby girl...that I’m having with the guy who broke me before, we also have a son together who is 3...I also have a daughter from a previous when I was dumb and 18....he lied to my face, cheated, hid so much from me, and two years later after all that mess I was A FUCKING IDIOT AND TOOK HIM BACK, immediately got pregnant the second month of working things out...moved in...transferred my daughters schooling....everything...all my stuff is in his house...we have no sex, he doesn’t hug me or kiss me....his life is cars, I have expressed all my hurt to him and how it’s hard to trust him because he still shows signs of hiding things...he doesn’t post me on his social media but he sure did that other girl.....in the past when we were together we deleted all social media because it caused so many issues...he snuck it behind my back and would delete it when he was around me....so now years later we have all the social media again...I asked him to please delete the girls who aren’t family or ones he doesn’t even know out of respect and i did the same on mine, besides on Instagram, he never deleted any random girls...and tonight I’m throwing up, cramping because of ALL NIGHTS he’s not home he’s apparently at a “car shop” yet Thursday night was “there” came home smelling like straight alcohol came home after 12 am...tonight is there again...so I posted a photo of myself earlier I did my makeup and took a photo because I never feel pretty anymore...so just now he sees it and sees 3 likes from guys THAT I KNOW WHO I DONT EVEN TALK TO...yet he has girls liking all his stuff still ...mind you him and I are both almost FUCKING 30! And of all nights he sends me a screen shot of the likes tells me fuck you and blocks me off everything....I am livid, I am sobbing to where my eyes are swollen, and here i am stuck at his house that I’ve been living at the last 9 months...set up everything in this room for the baby and now I just want to move back in with my parents because I have no where else to go! I’m not sure how much a moving company is, all I know is I can’t do this again...no matter how much I love him and do for him he doesn’t care about me or how he treats me! I cook, clean, I stay home, I do his laundry, I do IT ALL! While he’s never home or purposely avoids coming home, we barely even text. I’m hurting right now and I know this is all over the place and I’m so sorry about that, I just literally have no one to talk to or turn to....I need advice...solid advice...I feel like a bad mom having to transfer my daughters school ...I had to do that often in the past when I’d leave his ass on and off...it’s the same two schools also, and my daughter LOVES her school, has friends and loves her teacher, this is just complete bullshit...
