Little Secrets Between Friends - Reed Mary Kelly

Ella has been in love with Tyler, her best friend, for as long as she can remember. He knows nothing of her feelings, and she's determined to keep them secret at all costs.
Things change however when one evening, in a moment of weakness, she expresses all her frustrations on a blog. When she realizes the magnitude of the chaos she's created, it's already too late; the blog has been shared on most social networks.

As the cherry on the cake, Tyler finds out about the blog, and he's critical of the content and its author to say the least. But Ella's troubles have only just begun. Not only is she unable to defend herself, but Tyler sets out to discover the identity of the blog's author, and he's not the only one. Going from one surprise to the next, Ella realizes she may not be the only one hiding secrets.
