How do you handle conflict?

Recent realizing I used to be a person, I wanted to keep the peace /solution based when it came to people I love explosive when it came to people that I didn’t care very much about. Say something without thinking.
Say I didn’t know and now that I’m 30 I’m learning that I don’t give quick responses to things because I think about the stuff that I wanna say to each person but I know that they want a quick response in that moment, but I don’t wanna say the wrong thing Not politically correct but not to hinder the relationship just thinking

I feel like I’m still doing it wrong
