Let’s speak hypothetically, because it’s not real. We’re just speculating that a pope can dispense himself from the promise of celibacy. Canonists are discussing this and even they are not very aggressive on this topic, because it’s not a hot one.
If the pope could dispense himself from the promise of celibacy, he would still have to find a way to around the tradition of celibate bishops. For more than 1000 years, bishops have been celibate.
Let’s assume that he can get around that. He now gets married. He can’t dissolve his marriage. An anulment is a decree that the marriage never existed. It is not a disolition of a marriage. If there is really a marriage, the Church cannot dissolve it. A decree of nulity says that it looked like a marriage, but it really was not, because something was missing before the wedding and it was not present at the time of the wedding. Therefore, the couple are not truly married.
If a pope were married, he could not dissolve his marriage. He is bound by the sacrament like any other married person.
Again, we’re are speaking hypothetically. There is not law or theology that says the pope can dispense himself from celibacy.
We also have to keep in mind that there can be another complication. What happens when the pope is a religious? If he is a religious he not only has a promise of celibacy, but he also has a vow of celibacy. Religious make vows of celibacy until death. These vows are solemn, unlike the promise of celibacy that diocesan priests make.
Our current pope is not a religious. He is a secular priest. But we had John XXIII who was a Secular Franciscan and in vows. We’ve had Pius V who was a Dominican and many other popes who were religious or members of secular institutes with vows.
It’s probably best to leave well enough alone. LOL
