There was a man. Let’s call him John. He had a common law partner with two children, and they were together for a few years. But for some time, he wasn't happy. He was bitter and even snapped at his partner, Tessa. In his heart, he didn’t love her, even as much as he told himself that he should. John stayed with her, despite how he felt. It was the only solution, since Tessa was the mother of his children. He couldn’t leave her so she could eventually find someone else. The kids would be with her, and her boyfriend would be their new father. As much as he was miserable, his priority was his kids. They were the only thing that mattered to him.
