You and Dabi are together in a healthy relationship. You both love each other. There is just one problem. There is one thing Dabi loves more than you. The thought of killing his family, even if he himsekf died in the process

You didn't like the fact that dabi was willing to die, leave you behind, for his own selfish ideals. You brought this up, it escalated, and now you're screaming at eachother. " SO WHAT IF I DIE?! I shouldn't have gotten together with you in the first place."
