I love Dale and Andrea too and how much he cares about her, I think of them as just like really good friends
Rick wouldn't cheat on his wife, it's just that Rick&Andrea's noticeable chemistry was like oh my gosh and this fic is so beautiful and if Lori was just out of the picture entirely... but it would be hard starting a relationship in a Zombie filled earth anyways. Still it's fun to imagine though ♥
