It Was Always You — S.L. Sterling

Fresh out of an abusive relationship, Tatum packs up and goes to live closer to her brother.
A new life. New beginnings.
But when Parker -- her college sweetheart -- comes back around she's immediately divided between trying again or protecting her damaged heart.
Parker hasn't been able to get Tatum off his mind since the night he walked out of her life. Eight years of one night stands, along with sleepless nights, and the pain of losing her has virtually faded. But now she's moving back to town and all the emotions of the past come crashing in to drive him back to her.
Ex-boyfriends are real, though.
And hers becomes obsessed.
Tatum and Parker's rekindled love will be tested to its limits.
And worlds may come crashing down.
