There is nothing anonymous on the internet, NOTHING.
And yes its still betrayal, even when one thinks its āokā because its the internet and they think nobody in their real life will find out. Its still talking about your spouse behind their back. Once you put those words out there, it doesnāt matter whom is receiving them, its still bringing a third party into your marriage relationship.
Being in an abusive relationship though its not the same as someone just griping about their spouse because they had a fight, most people that want to talk about a fight with their spouse is looking for justification and are planning on āmaking upā with their spouse at some point. If someone in an abusive relationship is opening up to someone about their marriage, theyāve reached a point that they finally realize they need help and donāt know what else to do. Its a serious matter, where oneās safety/health is at stake. Theyāre not looking to gripe and make up with their spouse. They absolutely need someone to listen and give them support.
