Eligible Ex-husband

The man in the magazine spread, the one dubbed the most eligible bachelor, is my ex-husband. Six months ago, Simon's company was never more successful, just like our marriage was never emptier. I was a stay-at-home mom with a sugar daddy who had no time to pass the sugar or be a daddy. I asked for a divorce and he let me go, just like that. Now, I'm mending my broken heart and finding myself while being a strong role model for our girls.
But when my mom gets sick, I need help, and he's there like a superhero in a tailored suit. And when my mom recovers, he's still there, doing grocery runs and braiding our girls' hair. I don't want to hang my hopes on my workaholic ex just because he's suddenly wearing basketball shorts instead of designer threads or because he's giving me that look that melted my heart in college. Chemistry was never our problem.
I don't want to trust that he's changed only to find out that, once again, I'm not worth fighting for. He needs to prove that he'll be as ruthless about us as he is in the boardroom. Eligible Ex-husband was previously published under the same title in the Cocky Heroes World project. Some details have been changed, but the story is still the same.
