I also saw some news that Topuria and his wife (or ex-wife already) came to an agreement and I hope they have settled it well. If I remember it clearly, issue was in kids. Who will take kids, have time to visit them and all other bs. That is so low to manipulate with kids when partners have issues. If two idiots decided to split, they should do everything to make kids dont feel disadvantages of divorce. When he or she use "I will take kids" or "you will never see kids" as arguments, I would allow partner to punch other in face on law level.
But

I still dont understand why Topuria stopped training if he has troubles in family. Troubles does not mean he had to be 24/7 in court or with lawyers, or in endless discussion with partner. Readjust timetable and continue training.
Topuria didn't stop training. His was posting videos of his training. He paused fighting in UFC until he would settle this issue and I agree with him in this case because when you have such a trouble in your mind, it's hard to focus on the fight and weight cut (weight cut is too depressing).
As I said in the past, I still believe that Topuria was right in this case and that's why her wife withdrew the lawsuit or otherwise, I'm sure that she would fight. It's very common these days from women to claim false lawsuits and law is so terribly enforced that no one cares whether the man is innocent or not, they ruin the future of the man forever in 99% cases, even if there aren't facts that prove that man is guilty. Too many women abuse this and it has to be stopped!
