That’s the Way I Loved You by Carrie Aarons

Savannah: This town ain’t big enough for the two of us.
Which is why I left.
I was determined never to return to Hale, Texas. But when my new life in the Big Apple throws me a curve ball, I have to go back to tie up loose ends. One of those being him.
Jason Whitney was my first everything. Kiss, love, epic heartbreak. He shattered my world once upon a time, and apparently, he’s not done yet.
With old demons lurking around every corner, hightailing it out of my hometown is at the top of my list. Complete my unfinished business, and I get to leave any memory of my country existence behind.
Only, with each day I spend in it, with each moment I spend with him, I’m turning back into the girl who laid in the tall grass and swam in the creek all those years ago.
And I’m not sure that who I was is ready to let me go again.

Jason: We drew a line down the middle, and neither of us has crossed it.
That is, until Savannah Reese blew back into our hometown.
The day my high school sweetheart left, she took my whole heart with her. We promised each other forever, made plans that only teenagers could believe in, and crashed and burned on the grandest of scales.
When Savannah last saw me, I was a disgraced high school athlete. All washed up, I took it out on the only person who loved me. Then her world really fell apart, and I was too selfish to care.
Now she’s back, ready to sell the only remaining thing tying us to each other. I’ve been breaking my back for the last ten years not to think about her, not to be reminded of the love we shared.
But now that she’s right here, it’s impossible to forget how we used to be. Or let go of what we still are.
