Always Have by Claire Kingsley

Kylie’s best friend Braxton is the hottest man she’s ever known, with a rock hard body and a smile that melts the panties off every woman he meets.

Except Kylie. Mostly.
Kylie is anxious to get off the dating carousel and find something real. Despite the way Braxton tends to suck the air from her lungs, she knows he’s trouble. He’s just another player, and she’s tired of the game.

But Braxton isn’t the man she thinks.
The real reason he’s sh*t with women is simple. None of the women he’s with are the one he wants. None of them are Kylie.

He wants to love her in every way imaginable, but there’s always something in the way. So he stays her friend, watching her date men who are too stupid to realize how special she is. Always worried the next one won’t be. The next one will be the man who takes her from him forever.
Loving Kylie risks every fiber of their friendship, but losing her might be more than Braxton can take.
