My husband just left me.. New post updates

It wouldn't let me add to my other post and many have asked for updates.. I found out about the cheating through his snap chat. I found their conversations and confronted him and he admitted to talking to her for almost a month. He works with her (and she knew about me the whole time, knew I'm pregnant and knew I was getting a divorce before I did). Since i found out he has turned mean and cruel. He's not the same person anymore. He doesn't even look the same. Everything has been my fault. I "started problems", "made this bad" , "caused drama" blah blah blah... He has only saw our daughter for a total of 30 minutes in the last few days. Yesterday i found a receipt where he had bought me prenatal vitamins and him condoms on the same purchase (who could morally do that). The last few days I packed me and my daughter up and moved us to my home town by my family. All he kept saying was for me to hurry and get out of his house ( he had been staying at his dads) today he came by my house to supposedly see our daughter. All he said was hi and then started in on me because he couldn't find his xbox. I kept telling him i didn't know where it was so he said he was going to start going through my boxes and my house. I told him he needs to spend time with our daughter or just leave because i wasn't going to fight in front of her. He kept up asking for it and i kept saying i didn't know ( which I don't, I don't play video games) he got super mad and asked if this is how I wanted things to go and be. I told him I'm not doing anything, i didn't do anything and if he wasnt going to stop going through my house and spend time with our daughter he was going to leave and if he didn't I would have the police make him leave (I'm not going to be threatened and yelled at in front of my child). But of course he said since He's paying for everything he can do what he wants and i can't make him leave. He said since im turning this ugly I'll regret it, he'll take everything from me. My house, my kids and he's going to burn my life down. He said since I don't have a job ( don't because I'm about to have a baby and had been a SAHM) that it will be easy to take my kids. That idk what he's capable of that i will be sorry ( for him not finding his xbox i guess) I told him if he was going to be threatening and causing a hostile environment he was going to leave and that our daughter didn't need to be around that. He said he wasn't paying me another dime, told me he'd see me in court when he takes everything. I reminded him he cheated on me and left his family and made us move. He told me i cant prove he cheated and that him buying condoms doesn't prove anything either. Stupid me didn't record anything but I will be from now on. He finally left but now I'm terrified of what he'll do. He's so anger stricken and threatening to burn my life down, does that mean my house? Or just a metaphor like just making my life miserable? This all turned so ugly so fast and im scared. I'm contacting a lawyer tomorrow. But idk what else to do. I'm so hurt. He was so worried about an Xbox he didn't care to spend time with our daughter. She was devastated. I'm going to get a job as soon as I'm cleared from the doctor. And I'm going to get my name off everything of his I can for now. I opened my own bank account. I'm scared to go to court and lose my babies or he get them all the time and they be mixed into his single lifestyle of drinking, parties and woman. And when i have our baby I don't want him there now that i see this side of him. I can't be comfortable with him holding my baby knowing all the threats he's said. I'm changing my locks and securing my windows. He literally is like a crazy mad man that looked like he was out for blood when he left. I have a hand gun just in case.. Why did this have to happen and be ugly all because I found out his secret? He also accused me of stealing money from his vehicle ( haven't been near his vehicle since he left) but I'm really considering taking the money from our bank account together so I know I have something to help pay for my babies until i can hopefully get child support.

*UPDATE* since writing last (Sunday the 3rd its now Wednesday the 6th) he hasn't seen our daughter, hasn't asked about the baby, talked to our daughter a couple times on the phone but less than 5 minutes each time.. He cleaned out our savings and checking account before i could get to any of it but not before i saw on our statement he is buying his girlfriend steak dinners, alcohol and renting movies. And who knows what else now that he has all the cash ( which I'm sure he made a new account and put it all there) she's been at his house ( the one i own with him) playing house.. When I moved out of our house i took everything of mine, my daughter, baby, everything he said I could and everything I thought i would need to properly raise my girls. Well that pissed him off and he accused me of taking everything ( I left his stuff and only his stuff) so because of that he told me he is for sure not paying a dime towards keeping my house paid for. I applied for assistance through the state and my family is helping me so I should be ok until I'm off maternity leave. I've begged him to stay civil with me for our girls but he refuses since " I took everything". I'm really sad for them because he won't do it even for our children. I don't want them to grow up with parents who Are so hostile. He's still so angry with me. The only communication I'm having now is for our children. I'm too angry about him cheating and leaving me for a 21 year old party animal to even consider taking him back ever. It's disgusting and makes me want to hurl. I know I'll always love him but the man I loved is gone. This man is a complete stranger. Just taking it day by day. I think the anger is helping kill the heartache, I haven't cried in a couple days (not saying I won't again) but the images of them together keep flashing through my mind. It's been so hard. I'm getting stronger for my girls. I have an appointment Friday with a lawyer to get this ball rolling.
