Anyone know this one??

Girl is in bad relationship she calls her bestfriend from hospital either the best friend calls her brother/cousin/ guy friend to come help her move the main girl to where they live. The main girl kinda hasn’t spoken to her family well they all stop there to get some stuff. I remember the guy is a single dad and I think a hot rod and the kid really takes to the main girl while she is in hospital and climbs in her bed. And they sit together on the drive to where ever they live. The kid is a little girl

Maybe she also has broken ribs and the main guy tells little girl not to lean on her.
In the car on drive to where they all are going the little girl and main girl lean on each other to sleep I do know the little girl is still in booster seat/car seat

It starts with her in the hospital I believe!

I think there is a lot of the main guys family and that her family eventually moves to be closer and I feel like maybe I remember the one who hurt her either showing up at her family house or something.

I’m pretty sure it’s a series maybe a second book or the first in it.
