Im scared my mom will hate me if i go home now (runaway, stepdad,mom)?

I'm your age, but here's my opinion. You are an adult now, so go, and see your mom. She needs to know you survived, and she needs to meet her grandson. As regard her husband, he will avoid you, I think, and if he doesn't, you could put him in prison, so take no sh/t from him. Let people know your whereabouts if you do visit your mother. You are a beautiful person, I believe. Good luck with your life.
