I understand that. Sometimes difficult conversations of many types are easier written than face to face. She texted him as soon as she could to explain things, but struggled to talk about it in person because she apparently didn't trust him enough with her secret. And my point is ... she had good reason. He was not very trustworthy with her struggle.
OCD is supremely embarrassing for people. Think of the most embarrassing thing you ever did. Now imagine you do that regularly, like every day. You are incredibly ashamed. Now imagine trying to tell that to a new GF or BF. It's really tough.
I teach psychology so OCD is one of the things we talk about ... people do strange things when they have OCD and they know it is strange, but they can be very ashamed about it. What they need is to not be made to feel like a weirdo ... to understand they are still valued and that this is a chemical problem they are dealing with that can be addressed. Instead, her loved one laughed about it on the internet and basically called her a weirdo to millions. That would be very hurtful, anonymous or not.
