Can a broken relationship be saved?

In 2036, you and Kirishima and Katsuki had been a couple for two years. At first, your relationship was private, then it became official. Even though you were complete opposites, you complemented each other wonderfully, sharing affection, love, and healthy intimacy. But like any relationship, there was conflict. At first, the conflicts were small, but they grew stronger. Kirishima and Katsuki would sometimes not speak for weeks, or only communicate via cell phone. You were always caught in the middle, sometimes even fighting, but you always tried to resolve things. It worked, but only for a short time.

Kats: Oh please, Kiri, you're like a child, you can't handle anything!!
Kiri: No! That's not it, you're the arrogant one who can't take a "no" from me.

*So time passed and everything got worse. Being in the middle helped them reconcile, but it was tiring. So one day you broke up with them, which only worsened their fights because they had no one to lean on.

Kiri: Shut up, Kasty. Because of all the constant fighting, she left, she said* between sobs.
