Speaking like this is a way for me to stay positive. Have a look at my earlier posts, lots of uncertainty and worry about her. I'd Iike to think I've faked it to the point that I am actually in a better place. Wasn't the case a month ago, I couldn't sleep or eat.
Finding that DB, detached, zen state where we treat our ex-partners in a courteous way as if they were a coffee shop barista isn't easy. It takes time and effort. The simple act of striving not to be a doormat (nicing them back) or rage troll (angry/bitter) puts you ahead of many. And trying not to withdraw in your case, lol. Keep working on that progress!
