You perhaps want to read some books on the theology of the Trinity as taught throughout the centuries by the Catholic Church. It is difficult for us to craft appropriate answers. At least for me. All of what you say has been already addressed, literally ad nauseam. You are not the first one that ponders over these things!
It is impossible to assert what you assert, for it is rooted on an erroneous understanding of the nature of God.
I’ll try to express a very basic idea here, bear with me.
The concept of “person” is only definable within the indivisible unity of God’s nature with regards to the origin of each person.
God the Father is the Creator of all things.
When we think of ourselves, we have an image of ourselves in mind, an imperfect image that is destined to disappear as other thoughts arise. When God the Father thinks of Himself, this Thought is a perfect thought, and is the Son, the living Word of God, who would say:
The Son can do nothing of his own accord, but only what he sees the Father doing.
If you have seen me, you have seen the Father, for I and the Father are one.
Thus the Son is generated, not created, consubstantial with the Father, “light from light”, “true God from true God”.
Indeed through revelation we know that “everything was made through Him” (the Son) “and without Him nothing was made”. We also know that He said: “the Father does not judge anyone, but has given all judgment to the Son”. Indeed, the Father gives everything to the Son as His divine inheritance, and the Son says: “All power has been given to me in heaven, on earth, and under the earth”. This is God’s will, because in the Son the Father is well-pleased, and because in the Son all of God’s children are gathered into one mystical Body, of which the Son is Head.
As it is natural, the Father and the Son, acknowledging each other, love each other. When this occurs between creatures, this love is strong indeed, but imperfect. Between the Father and the Son, who in truth are still One God, this love is perfect, in fact, is a living love and a perfect bound. This love is what is called the Holy Spirit, love of the Father and the Son, who proceeds from the Father and the Son, and with the Father and the Son receives one same adoration and glory. It is the Holy Spirit, this love, which unites the One nature of God. It is this Spirit who inspires the prophets to speak of God, and of the Father and the Son. And if you read the Bible, especially Psalms and Isaiah, you will find many of this dialogues between the Father and the Son narrated by the Holy Spirit through the prophets.
Do understand that the Son, as God and as one with the Father and the Holy Spirit, existed even before time itself came into existence. Only at a certain moment in time did the Son take human flesh to fulfill the salvation of mankind:
I did not come to condemn the world, but that the world may be saved through me.
By the will of the Father and the power of the Holy Spirit was the Son himself to become human. In doing this, the Spirit that united the Father and the Son now reached throughout all humanity: this Spirit, though the Son, who had become true man, extended to all of humanity to gather them into one:
As the Father has loved me, so I have loved you. Remain in my love.
I want them to be one, Father, just like you and I are one.
This is why when we address God in the most excellent prayer of Christianity, we say at one point to the Father, referring to the Son:
through Him, with Him, and in Him, to you, God the Father Almighty, in the unity of the Holy Spirit, all honor and glory forever and ever.
This literally means that after the incarnation of the Son, by being united with Him we partake of the divine nature. For this reason the apostles of the Son were very explicit in their teachings: “your body is not your own, but the temple of the Holy Spirit.” And they taught that there is only one body, of which we are all members, and of which the Son is head."
I hope that any of the above has provided some insight. Remember that it is literally impossible for human beings to understand the divine mystery of God’s nature. It is only through revelation that we begin to grasp the trinitarian nature of God, but even this way we cannot express it if not partially. But our knowledge, while limited, is incredibly sound.
