To me, the annulment process in and of itself doesn't seem problematic.
In the previous 10 year period 1,200,000 American Catholics have been told by the Catholic Church that their supposed marriages were non-existent from Day One. Despite maybe decades of being "one in the flesh" the Church tells them they were never married and cohabitation must cease.
*That* is problematic!
This is patently an absurd commentary that you offer here. Why you make it seem that the Church has divided this otherwise loving union of one man, one women in wedded bliss....Well Father, it is more like wedded blisters!!
People who get annulments are already divorced. They are already, and often, bitterly opposed one to the other, and anyone who has tried to keep them together, I might add, or to those who supported the aggrieved one in a messy grab for resources at the end!! There's already hate-aplenty to go around in many of the cases, perhaps most of them.
Overall mind you, in cases where annulments have been granted, there's been physical and mental abuse, substance abuse, adultery, same-sex attraction issues, physical abhorrence, psychological rejection that can range from severe to absolute, there's been screaming and shouting and recriminations and lies, battered children on all levels or no children at all....and on and on and on. Many of them, married for decades, have not shared the same bed for decades, or only to serve the need for appearances while they philandered elsewhere!!...so much for "one flesh" Father.
