Help:(

I'm 21 and my SO is 22. We live with his dad, his brother, his dad's gf and her son. I hate it here and I do not wanna raise my child in this house. I don't want my kid to be parented by other people, like I know he or she is gonna! It's been bothering me so much so today I finally got the courage to talk to my SO about moving out and not being here when the baby comes, and he flipped out. He broke his tv and said I could leave whenever. He told me I bashed his family when I didn't! I tried to do the opposite and it blew up in my face. I'm so upset right now and don't know what to say or do. I wanna move back home to my parents, until I can find a place of my own. I'm at a loss. Anyone else been in this situation?! :(
