His taking her to mental health doctors and counseling was ignoring it?
I know a man who has been a faithful, giving, and loving husband for 40 years of marriage, to a wife who struggled for most of those years with varying levels of mental issues and extended mental health counseling and treatments. Over the years he caught hell from some relatives and her friends for either going too far or not doing enough. And the wife was VERY good at playing the manipulation, pity, and gossip games. Sometimes there just isn't a perfect answer or approach, with a severe downside to any decision.
Am not at all directing this next sentence at you, but on these threads I've seen a lot of the same gullible and/or malicious gossipy jumping to false conclusions and slander that I saw in some of her circle. And it makes my blood boil.
Don't get wrong. I am not making excuses for her at all. I think they should BOTH be in jail.
