NLW,
My dad is the EXACT same way. He gives you just a bit of info as bait and reels you into his pity party.

I'm not saying be heartless and cold. But detach lovingly. If he brings it up to you then you can say something that doesn't pull you in.

I hate that he can do this to the kids but in time they will know they're father so well they won't bite.
