Charlie obviously needed more time to confront his own feelings about whether or not he felt capable of training and competing at a high level. Obviously, his emotional and physical well-being are important and few people would say otherwise. If he had perhaps taken longer to reflect before committing to Lubov, then they could have had what many other skaters have had: a tryout with potential, but not a partnership pursued.
That happens when skaters are in a place of real understanding of what their next steps will be. Unfortunately, sometimes skaters are in flux and need more time to weigh in on uncertainties. Training in Canada with the restrictions they had at the time was a tremendously difficult position to be in. Added extra layers of complications, which is, of course, unfair.
I removed the bits about your experience as a parent as though it is interesting, and I can empathize with the sensitivities one could feel about their daughter involved in the sport, Lubov and Charlie are grown ups, and part from the very elite. I don't think it's very fair to project what some skating families are going through on to Charlie here. As a matter of fact, he comes from a skating family himself, his mom is a figure skating coach.
About Charlie needing more time :
Charlie
did take a long time to heal himself, and also had 3 tryouts before settling down with Lubov. After the games in 2018, he was getting ready to skate with Julianne for another cycle. They both had issues, he could no longer be in that environment and left the sport in the middle of the summer. He only started skating with Lubov for the 2019-20 season ! That's pretty much a full season he sat out. That's a quarter of the cycle and basically a whole lifetime in elite figure skating. Any longer and he was never coming back ! He did try his utmost, in my opinion, to heal himself, rest, and get back into it. At that point, he probably felt that the new environment, the new coaching team, the new partner, even a rather different approach to skating may revive his passion...
However, they didn't skate well at Nationals, They didn't qualify for worlds, placing 3rd. They only placed 7th at 4CC. He didn't feel great nor did he skate great. He was probably already burned out. COVID hit and worlds were canceled. THEN he announced it to Lubov. They didn't have to deal with training during Covid times... he pretty much retired when things shut down completely in Canada.
I felt from your post that the timeline of events needed some clarification. Charlie did take time to heal. Charlie did take time to choose the right environment and new partner for him. Charlie was excited about his comeback with Lubov. Come Nationals, he wasn't feeling it.
Sometimes, the training will feel right and exciting but when the skaters get back into the competition pressure (like Nationals would do, qualifying for worlds at home), it may trigger the ill feeling that he has referred to in the article.
