I've asked God many times to move me to the True Church without pain and with happiness. So far, His answer has been: "Stay where you are for now; I'll get back to you!"
Maybe this is the time you can move on. Orthodox Byzantine is living Orthodox outside Orthodox Church. It does not make much sense.
My experience is this. I wanted to become protestant because I was thinking God is there and I knew the verse: If you love your parents more than me you are not worthy of me. So I said, God is there because I see the works, there is where I go, after God. However there were 30 000 denominations and I could not buy One Truth = 30 000 truths conflicting. So I said, now I have to find the protestant denomination that has truth.
So I was thinking myself, would it be the Church with most people? Arianism had that and was not the true Church.
Would be the one with best buildings? Arianism had that and was not the true Church.
Fortunately I had the idea to ask God.Dear God please show me the true Church and on and on and once I heard a thought, You are in the true Church and this is why I send Holy Light there every year.
How I can be sure it was God? Somehow I am sure.
Also I read that muslims, many of them , asked God to tell them the truth and Jesus came to them in dreams and told, Christianity is the true religion.
Somehow God is saying knock and it will be open ask and it will be given so ask and God will respond in a way it is understandable to you and your experience. I am sure if you ask God to move you without pain to the new religion, God will move you without pain. Somehow out of blue something will happen that will make you go to the best religion.
So continue praying and God will tell you when to jump. Maybe now you have to solve other problems or there is something that God knows this is not the appropriate time to jump. Maybe God wiil do some work that will make things easier. You may want to prepare people around , see how they will react to you jumping so it will have happy ending as you asked. If people around you love you, then they will not separate you from God or best religion.
