Who do I choose when I love them both?

I hate being put in the middle, but my parents refuse to speak. I can tell my mom more and she lives alone. My dad is bias and has 4 other children. My mom has my dog, but my dad has my sisters. Sometimes it feels like my dad hates me but if i live with my mom i wont ever get to see my friends from this town with my dad in it. If I leave my sisters will hate me but my mom raised me. My dad didn't even want me for 12 years. I hate that they wont talk and I was just going to leave to go live with my mom. But my dad talked to me and said he wants me to stay with him but my mom is lonely... who do i pick???
