Oh I am the same. If he emails I reply to only what needs to be - like this week he emailed me, asked if I'd heard from child support, asked about pickup times for the kids this weekend, and then asked how much car was after an accident last week. I replied very to the point, but didn't reply to the bit about my car - is none of his business.

Also while he is here I just say hi, tell him what he needs to know re the kids and then bye. I agree while he is pursuing the OW we have nothing to talk about, other then our kids and the house (which I won't even discuss yet anyway).
