is it weird for me to be jealous of my friends families?

[Kayyyy]

im 15. my parents seperated when i was 3 and got officially divorce when i was 7. when i was 10 my mom got remarried. unfortunately we later found out he ws an alcoholic and she's still married to the pathetic douchebag for financial reasons. shes a teacher and having trouble finding a job. he emotionally and mentally abuses us. one time he slapped my mom in the face and a few weeks ago threw a flashlight at my sister and it hit her in the face and made a small bruise. we've stayed at hotels a lot and called the cops on him. i want to move in qith my dad in the midwest but thats another story.

anyways when i see my friends families i feel sad and jealous. their dads are always nice and it seems like they are all really close and never any horrible fights. is it wrong for me to feel this way?
