Having a child with the wrong man brings heartbreak over and over and over. Even after you two split up, he'll disappoint her, which will break your heart too. You'll make exciting weekend plans with her, and suddenly, he'll call and get her to change her mind so she goes with him instead. And that'll break your heart. You were looking forward to this weekend all week, and he just prances up and steals her. Heartbreak. The hours spent trying to explain why daddy isn't around. Heartbreak for you both.
It's just bad. All bad. If I knew then what I know now, I might not have a child... That's sad. But one thing's for sure, I wouldn't have a child with an occasional father.
