Hi Jamaicamecrazy (just really read your name and love it!) I am not a catholic, but was raised in a very conservative church so I know what you are talking about. I suffer from the same questions as you. What I have learned from the crazy train is that God is a loving God. He never intended for life to be like this or for a union that He has blessed to be unhealthy. I believe that He gives us a choice. It says in the Bible that He hates Divorce and I believed for a long time this meant come Hell or high water we are not to divorce or we would almost be commiting the unpardonable sin. But I have also been doing alot of studying and believe that once our partner becomes a person that God never intended them to be, we become unequally yoked with that person. Just as the Bible is against divorce, it has a lot to say about a person that becomes an alcoholic. Read Proverbs 23:30-35. I hope this helps and my appologies if this isnt what you were looking for.
