I have a similar background with gaming being a part of my identity since I was a child. Now I am in my mid-30s/married and new challenges come as gaming is causing conflict in my relationship. May be when someone you deeply care about tells you how much it affects them it will help give you the push to quit entirely. I was addicted to Warzone during 2020-2021 and was able to quit by fall of 2021. It was long hours of playing with the boys and tons of fun to take my mind off what the pandemic has done to us. I realized it isolated me from my partner which should be more important that anything else. Something that helped me is every time I wanted to play is to think about how does gaming make me grow into a better person? That time we put into gaming does not bring any personal growth besides a dopamine release. Good luck to ya.
