Pregnant single homeless mother on bedrest

In need of help.
I never thought this would be my life but here I am today, admitting that somehow it has spun out of control. Baby due in less then a month and I am currently a homeless mother, on bedrest due August.
Meanwhile my life prior to this unfair position I was in an established relationship with the father of my expecting baby.
Somewhere along the beginning of this pregnancy the father of my new baby decided to emotionally pull out of the relationship and dislike my previous children, not abusive or crazy but consistently giving me every reason to understand as a mother, a very unfit lifestyle for my amazing girls. While my exit was not what I wanted and truly upsetting, You know when you need to pack up and leave. The father of my baby unexpectanly became idolized by gaining new relationships and quickly and disrespectfully just left me hanging.
This was beyond my control and I walked away knowing there was to be struggle up ahead but I cannot live with a man who belittles my children and with every effort I had in my bones to try to be open minded and weigh out disagreements, however there was nothing could change his unloyal intentions.
While the father of child owns a home, owns his own business, and has an empty house he rents next door to the home he owns, the funds he does provide he feels is adequate enough for my survival under the bed ridden circumstances of this pregnancy. They are in no way close enough to get me in a home and establish safety or comfort where I need to come to after baby is born. I have every intention to seek employment opportunities immediately after baby is born but without a home and a broke down car, little to no resources, I have my hands tied.
I have been staying with family in a small home temporarily as I have been placed on bedrest due to 3 different pre labor occurrences during this pregnancy.
I would be forever grateful if someone could help as I am not one who is use to this lifestyle and I have no idea where to turn. I have reached out to every government resource and all housing authorities are closed. I'm tired of begging this man to not withhold what I need and flip flop from day to day. My only option at this point is to hop around homeless shelters which even these options are limited. I would never wish this upon anyone and during my life when I have been able to help, I have donated my efforts to help those in need. Now it is my life and I am very confused to where to go and do. I wish I could ask for more from my previous partner who is perfectly financially capable of putting me in a home but is limiting what he hands out due to this falling out of a relationship.
I know after having a baby takes time to heal but I am more then willing to skip the healing process and do whatever I can selflessly to make sure me and my children are safe and no longer sleeping on the ground at other people's homes. Again I am very grateful for any help. And I would be absolutely willing to be of assistance later to anyone who donates at this critical time of my life.
I can't believe I am asking for this but thank you so much.
Many blessings.
