Pregnant and homeless

Well my now ex boyfriend was told by his friends that I cheated on him and he now denies that our baby is his. On December 1st he kicked us out in the rain at 2AM with no remorse after he attacked me and has even taken to goin on Facebook and Instagram to shame and defame me. The sad part is that as much as I hate him I love him. I'm now in PATH which is a homeless shelter for families  and pregnant women and I've never been so scared in my life this is hard and I just want to be able to do right by my baby
