Divorce for Withholding Affection | LegalZoom: Legal Info
Withholding Affection is the same as abandonment and is legal cause for an at fault divorce.
...and your link doesn't even talk about withholding affection. It talks about "No Fault Divorce" meaning that you don't even need a reason to get a divorce anymore.
Withholding Affection = lack of interest in things that are important to you, lack of concern for your well-being, being divisive against your friends and freedoms in life, etc. The fundamental elements needed to have a well rounded relationship on an emotional level with the intent of being hurtful.
You can have sex and still be in a relationship where Affection is being withheld. Often, women who are in an emotionally abusive relationship DO have sex - and in that type of environment it's considered to be transactional, not affectionate.
Please understand that.
