>It's really stressing me out because of how confusing the situation is
Take it easy. Just go visit the Churches around you and observe. Maybe you will find a place where you will be able to say Did not my heart burn within me? (Luke 24:32) Have trust in God that he will direct you.

>nobody violated the 3rd Council of Constantinople since that isn't in those canons,
In the Orthodox Church this council counts as Ecumenical and its canons are binding.
> which is nice for the Christians involved
No, this isn't nice for the Orthodox Christians involved. Fortunately, at present in the Orthodox Church disorders like this do not happen as often as they have happened in the past.

>Many Orthodox have Catholic and Protestant relatives as well
Do not think that I have come to bring peace to the earth. I have not come to bring peace, but a sword. For I have come to set a man against his father, and a daughter against her mother, and a daughter-in-law against her mother-in-law. And a person’s enemies will be those of his own household. (Matthew 10:34)
>Constantinople and Rome have mutually acknowledged their status as sister churches
Rome has acknowledged the Orthodox Church as a sister Church. In the Orthodox Church, however, the bishop of Constantinople has no authority do make the same decision so this remains his personal opinion.
>So it's understandable that many bishops wouldn't make such a strict application of the canons against praying with heretics
Such bishops are very few. Moreover, they don't like to announce their actions publicly because they know the reaction that will follow. This is especially true for the bishops that are not of the Patriarchate of Constantinople.
