Separated, new baby, but still hopeful

[P17]

I definitely wouldn't let him know directly - ie., don't tell him.

Leave the leaflet, sticker, flyer, whatever lying around and if he mentions it great. If not then let it lie. He will mention it though, I promise.

Bear in mind he will ask at some point where you are going. You just need to say a class / dance class. Let him wonder and find the rest.

The point is to be mysterious without avoiding him. If you avoid him it will look like a deliberate ploy.

I have been reading your 'ramblings' from the start. Your H is a fool. But then we all know that. It doesn't matter what we think though, only what he thinks. I would give my right arm to be in his position (if you see what I mean!)
