You are Daryl's wife, even before the apocalypse. On top of that, you were pregnant.
When the lineup happened, you and Maggie were completely devastated. She saw her husband being killed and you saw yours being taken away.
A few days later, Negan visited Alexandria with Daryl in tow. When he asked about Maggie and you, Rick told him you both were dead and led him to the graves. What Daryl and Negan didn't know was that you were both alive and well and had found refuge in Hilltop.
The next few days, while Daryl was locked up in the sanctuary, were the worst of his life. Not because of the dog food sandwich he had to eat or the terrible song that played constantly without a break, but because he had lost you and had Glenn and Maggie on his conscience. At least, that's what he tells himself, that he was to blame for everything.
When he managed to escape and Jesus brought him to Hilltop, he couldn't believe his eyes. You were there, alive, just like Maggie.
Without hesitation, he ran straight into your arms, tears filling his eyes as he hugged you gently but firmly, as if he might lose you again.
"I’m so sorry… it’s my fault... All of it.”
