I know that divorce is frowned upon by God. There are exceptions to this, abuse being one of them, along with adultery.
However, when one reads through the Bible, "marital unfaithfulness" gets thrown into the mix. I have run across items referring to this aspect from Matthew here: "What is the exception clause?" Another with several translations is on biblehub.com. So it looks like there are two separate entries: Matthew 5:32 and Matthew 19:9.
Would "marital unfaithfulness" encompass emotional abandonment? I do not refer to one of the partners having an emotional affair, but more along the lines of just not being there for their spouse emotionally.
Or does this fall more along the lines of abuse, and does God see emotional abuse as he does physical abuse, as wrong?
