As Long As You Love Me - Dana LeCheminant

After fifteen years, straight-laced Brennon Ashworth is finally over his high school crush. Or so he thought.

After his best friend signs him up for speed dating, he inadvertently compares every woman to Molly, the carefree and vivacious girl who broke his heart. Ever since she left, he has done everything he can to make life predictable so he isn't hurt again, even if that means life gets a little boring. When Molly shows up out of the blue, his carefully controlled life is thrown into chaos, and the masks he's been wearing no longer seem to fit. She knows him better than anyone, so he can't hide from Molly like he does the rest of the world. And that terrifies him.

When his pseudo-family, the Davenports, are in trouble, Brennon reluctantly teams up with Molly to find the truth and prays she isn't lying when she says she won't hurt him again.

Because he's as much in love with her as ever, and he's not sure he can survive another heartbreak.
