I am ashamed

I had sex with someone I thought I loved and he loved me. He mistreated me. I lost my virginity to him now I'm pregnant he abused me and he got scared started running further away :/ I had no one but God. My boyfriend doesn't believe in our savior. I know the bible says its acceptable if the non believer leaves. But now I show up pregnant to my parents house. I'm pregnant no husband and guy is a as#hole. I stopped going to church, I haven't shown myself around my parents friends. My mother I think she's so ashamed she wants to leave the state. So honestly my parents bad behavior has me feeling down. I want to laugh, I want to smile, I want to talk about the baby and be a family but its like everything is hidden I hide my belly. I just don't know what to do anymore or what to say so my parents understand I want this baby, I made a mistake, but what can I do. I don't want to be ashamed anymore I want to say yes I'm pregnant I want to go to church.
