Personally I think a lot of it just gets down to the sad society we live in. If the parish churches told couples they needed to undergo spiritual/marital counseling with their priest for several months first before even considering granting a divorce, many couples would leave the Church and go elsewhere. Yeah, that's sad. But it's true. The Catholic Church is no better though. Even though Catholicism "doesn't have divorce," the marriage tribunals in the U.S. amount to nothing but a committee of rubber-stampers who could care less. Basically everyone gets through it. So on paper the Catholics look tough on the issue, in real life, not so much. I guess Orthodoxy seeks to be more honest in a broken society, but that still offers me little comfort. If this issue is troubling you, though, then I suggest reading a book called "Marriage: An Orthodox Perspective" by one of my favorite priests of the 20th Century--Father Meyendorff. He was my own priest's Confessor Priest at seminary in the early 1980's!!! Father Meyendorff's book "Primacy of Peter" basically cemented my conversion to the East. This book about marriage was excellent as well. It focuses on the practicality of marriage and family and how economia plays into it. Get the book used for $8.00 or check it out at the library somewhere. Great book that might close some gaps for you.
But I will say, staying Catholic won't solve the angst against divorce either.
In the end, except for the practicality of having many Catholic parishes near my home within reasonable range, there was not ONE SINGLE REASON for me to stay Catholic. Divorce was low on my food chain, but I think the Orthodox explanation from Meyendorff helped. In addition, I've learned in my 42 brief years on this Earth that DELIVERY and STATEMENT OF FAITH are two different things. There isn't one parish in the U.S. or on this planet that doesn't have some issue or drama. Trust me.
