(I'm not sure if I'm posting this in the correct place)
My ex partner and I are friendly, we get along okay and can have decent conversations. His gf of 3 years has been okay towards me too.
There is one thing that really grinds my gears... She has a habit of telling me how to parent. From day one she has always snuck things into the conversation about how to parent. (she has no kids) They have DS every fortnight for 2 nights.
I have just been ignoring it completely. But she doesn't stop. For example, DS has head lice and last night I received an inbox from her saying "I think its a good idea that you wash his bed and school hat"..... Which obviously I had already washed that day. I get so peeved off by it that I just don't reply.
If it were my ex partner inboxing / saying it, it wouldn't bother me but he never says anything to me and she does.
How do others deal with it!!? I feel like blurting something out like "Do I tell you how to do your job?" or "When you have kids darling, then come and give me advice". Obviously I don't want to cause tension as our co parenting relationship is okay as it is but I also don't want to listen to it for another 20 years.
