Wait for Me by Max Hudson

Simon was never supposed to be gay. Thanks to his father, Simon learned a valuable lesson when he was young. Being gay might be something that other people could make work, but he couldn’t. After his abusive father made the boy that he liked move away, Simon realized that he would never be able to be true to himself and that being into other boys was simply not an option.
That’s why, even after his father dies, he decides to start dating one of his coworkers. She’s beautiful, she’s smart, she’s funny—there’s just one problem. She’s a girl. But Simon needs a beard because people are starting to talk and he can’t have people knowing that he prefers the company of his own gender.

Before he can end their relationship, his girlfriend gets pregnant and Simon enters an unhappy marriage that lasts far longer than it should. When he’s finally going through a divorce, he meets Aiden.
The opposite of him, Aiden is younger, flamboyant, and the definition of out and proud. Simon’s interest in him never wavers, and Aiden seems to be interested right back. Except Simon is still firmly in the closet, partly terrified that his child, who is starting to have his own opinions and life, will have a hard time because of his father’s sexuality.
Suddenly, and for the first time in his life, Simon finds himself having to choose between being true to himself and his child’s happiness. Aiden’s patience is wearing thin. As an out and proud gay man, he hates the idea of being with someone who is still in the closet.

But despite all his inner turmoil, Simon manages to win Aiden over. Under one condition, and one condition only: he needs to tell his son.
Except that every time that he goes to do that, no words come out of his mouth. It doesn’t matter how much Aiden might love him. He can’t wait forever.
Simon needs to decide whether to protect his son or to be with the man that he loves.
