The Catholic Church vs Orthodoxy. Part 3. Split

[Jonikster]

Hello.
Please sorry for my english.
My name is Constantine.
I was born in Orthodox Christianity. However, over time, I began to gravitate toward other faiths.
I would like to go to the Catholic, but there are things that I do not understand.
I would like to get a theological education, but the choice of denomination to do before.
I ask you to guide me to the right path.
I would like to ask about the 3 topics, but there is a maximum allowable number of characters 3200. That is why I divide it into 3 topics.
3. Split.
The Church of Rome shortly before the split (1045-1047) was at the same time three of the Pope (Benedict IX, Sylvester III and Gregory VI). This is also complicated by the case of reunification. On Sutriyskom Cathedral (1046) at the request of Henry III, all three popes were declared deposed. With the support of the Roman Emperor at the department established (in 1049) his relative - Leo IX to finish the job separation.
And here I heard two versions of the division:
Catholics often talk about the closure of the Latin churches in Constantinople in 1053 and that sokellary Patriarch Michael Cerularius ejected from the Shrine Latin sacred gifts and stomped their feet.
Point of view, most of the Orthodox that Michael Cerularius began to go against the Pope. For this reason, Pope Leo IX sent a legate to Constantinople, headed by Humbert.
"They did not tell me even the usual greetings, - says Mikhail Patriarch of Antioch - not favored to make the most simple bow, there was not the slightest sign of respect … All in all, surprising that they every repeat: we de came here not to you have to learn, but to teach you, you get to take our dogmas. "
I believe that the insertion of the Filioque in the Creed, East-West Schism in 1054 there past time mistake.
My final question is whether we can fix the mistakes of the past? Is it possible to undo some past Cathedrals theoretically?
Thanks in advance!

My final question is whether we can fix the mistakes of the past?

As I have posted before:

As a certain Austrian college professor who moved onto bigger things put it:

“Rome must not require more from the East with respect to the doctrine of primacy than what had been formulated and was lived in the first millennium . . . Rome need not ask for more. Reunion could take place in this context if, on the one hand, the East would cease to oppose as heretical the developments that took place in the West in the second millennium and would accept the Catholic Church as legitimate and orthodox in the form she had acquired in the course of that development, while, on the other hand, the West would recognize the Church of the East as orthodox and legitimate in the form she has always had.”
