I like the premise but it fell short for me

It started out so well. I love age gap romance between Holly and Nick. I also liked the May December angle of our main characters.
My issue with the book is that Nick was pining for Holly for years. He finally captures her attention despite her best efforts to keep him at arms length. The have a brief love affair in which she becomes pregnant. Then Nick decided that it was "to real" and dump her. It took great lengths on my part to finish reading this. I wanted to toss my kindle at Nick.
Despite my issues with the main characters I really liked Nicks dad Dominic and Holly's BFF.

I was given a copy through Novel Reviews for an honest review.
