My own cousins had an abusive father and he was perfectly happy to live out his life married but cheating on my Aunt, out drinking every night and gone every weekend spending all of their money. My aunt finally got a divorce and went into counseling with our Priest. She met a wonderful man, for her and her children, and they celebrated their 40th Wedding Anniversary this past summer. Do not compare that with Abortion!
There are times that separation and a civil divorce is justified but this does not invalidate the existing marriage. As Christians do we take the words of our Lord seriously or are we just play acting?
