Help me find this book it’s a high school romance y/a

so it’s a high school romance y/a - this is what I remember.

she was like a cheerleader or a volleyball player and her boyfriend was like the an of there football team she finds out he was cheating on her and doesn’t tell her friends she like goes silent form them she gets for a run were she bumps into the an or the rival school and hes swimming in the lake or something like that. they end up making like a summer bucket list and the like jump of a waterfall and climb like a water tower . after summer ends they stop talking and they reconnect and fall in love.

side notes I remember something about like her parents never being home and him having a crappy mum and a little sister - also before they reconnect they see each other at a party and the cops come and they run away together - also I think he had an Older brother who killed him self

I think there was a second book this is what remember.

the go off to college together and before they leave he gets into a huge fight with his mum and they leave for college she applies for the school volleyball team and gets in he’s on the football team. there’s like a group of wags for this football team. her ex boyfriend keeps showing up and stuff and her now boyfriend ends up getting hurt anyway thats about it i remember him going pro too aswell
