To be honest, ideally, he should retire after the season is over but he may have his own consideration to retire soon.
Barcelona have 5 center backs, without Pique, they will have 4 center backs only. Araujo and Kounde are injured, so Barcelona only has 2 available center-backs. I think Barcelona needs a new center-back urgently, they cannot rely on 2 center-backs since they have many remaining matches.

It's okay if he decided to resign in order to rebuild his family.
Barcelona's new central back was already in place to replace him.
