26 wks pregnant/husband walked out.

Sherise • 2 of my own...2 of his own...baby number 1 for us! #superexcited
The last time I have seen or heard from my husband was on Thursday, June 11th. Tried calling, texting him, no response. He said to me he was gonna pick up Chinese food and never showed up at home. I waited 24 hrs, called the police and filed a missing persons report. I then noticed that our bank account was cleaned out, $1600 gone. Taken out from different ATM's in area where we have never been or even have family. I feared the worst. I thought he was kidnapped, I thought he had a mental breakdown or some type of psychotic episode because he does suffer from anxiety/depression/OCD and was taking Paxil. I went all weekend worried, kept the police informed and nothing came about it. I finally talked to a different police officer who encouraged me to file an involuntary emergency admission to a hospital, just in case they did find him and he was unstable he can be assessed. I did. He finally shows up to work on Tuesday, June  16th. Didn't even come home, didn't call me, didn't check on our unborn son, I'm currently 26 weeks pregnant. The police arrested him and took him to the emergency room to be assessed. I got a call, left work and went to the hospital. He didn't want any visitors. So I waited until he was finished with the doctors and he saw me, ignored me and walked on by. I walked out behind of him and he kept on saying, "I don't have anything to say to you after this". I explained to him how worried I was, I was scared sick. He didn't care. 
All in all, the police told me to check his phone records, I did, it came back to a prostitute. I googled the number and found numerous pics of this woman. Her bio and her needs and what she is looking for in a man. I also found an address where she was located. The same location that the ATM transactions were made. I also got word from my husbands co workers that he was bragging about being with a hooker and it wasn't the first time. He also wanted to know where to pick up other women for sex. Nobody at his job knew he was married much less having a baby I was told.  I attempted to kick him out that night. Instead he slept in the second bedroom. 
He wasn't in the least bit remorseful, apologetic, or even showed any emotions towards me, much less our unborn son. I feel like I married a wolf in sheeps clothing. I'm devastated, I'm broken, I'm hurt, I'm tearful all the time. I'm so confused as to what happened, how could I have prevented it. Our baby was planned and for him to do this to us so he can please himself is just outrageous. 
I came home to a note saying that I wanted him to leave so he has found a place to go. I'm left with trying to support myself in every way and preparing to be a single parent. Also, our lease will be terminated in August, I'll be 36 weeks and making a move to somewhere to live. 
Need some advice, where do I start? How do I get over this hurt?
