What should i do after a conflict

An

Yes, a little fight, and this the first time, i kinda messed up his schedule for the day, and he really pissed about it. I did tried many time to say im sorry for doing that and will keep in mind about his schedule next time. But he still really angry for like the whole evening til night, this gave me anxiety, stress and a lots of crying, yeah. Until before bed time, he texted me that he didnt want to keep pissed like this forever cuz it’s not worth it, and “dont want to talk about it anymore” i reply ok, and something tells me that he still pissed.

Up to next morning we kinda sorted things out again, he asked whether or not did he overreacting, and i pointed out what’s wrong w him last night and what my fault r, etc, and he replied that he understood and will keep it in mind also.

But after everything happened, i felt like a disconnection between us… the conversation felt really awkward after that conflict.

What should i do?
