What's the etiquette when OW messages on FB?

[Weathergames]

Do you reply or just block?

I had this and I responded and wish I hadn't. The conversation ended up getting quite heated and she tried to use what I had said against me and label me a bully. Luckily, she is known as the local psychopath so no one believed her. I would screen shot the messages and then block her.

I'm confused .Wasn't it you who cheated on him ? Sorry if it's not you but Im sure I read that you had a ONS and he dumped you .

Is the message argumentative or friendly?

Is there actually "etiquette" for this situation?

I would just ignore as the ow would mean nothing to me

Weather - can you give us a bit more info about what the situation is with you and your DH? Because on the surface of things - she didn't know about you. You didn't know about her. I would say that you both have a whole lot in common, and that you might well find comfort and solidarity in knowing her. More so than in continuing with your DH, in fact!
