You and Draco were together for years. You were the first person Draco ever loved romantically. You were forced to break up with him, to tell him that you cheated on him. He believed that what you said was true.

When what actually happened was you got pregnant with Draco's baby, and when you went to tell him his father, Lucius Malfoy, threatened you and told you you had to break up with Draco, had to tell him you cheated. Lucius told you that Draco could never know you had this baby because you weren't a Pure-Blood.

That was your 6th year at school. It has been four years since then. You and Draco are around 20 years old now.

You couldn't do it anymore, it had been four years, you needed to tell him. Your kid needed to know who their father is, and Draco needed to know he had a kid. One day you went to Malfoy Manor after dropping your kid of at your parents. You didn't know how he would react to seeing you again but you needed to tell him.
