Well, at least he's talking to you, right?

If he does see your postings, he'll see that they aren't steamy love letters, but genuine concerns. There is some stuff in here that he may not find flattering, but that's what you risk when you read someone's journal.

Maybe he'll cruise the site and get some ideas on marriage building too?

It's out of your control, so I would advise if anything comes back to haunt you... validate, don't justify and listen to what he says. Then maybe he won't feel threatened by the site.

At any rate, at least he'll see that you're talking to a housewife named Anna, not a male model named Pedro!
