What is going on here... and what do I do?

[LIO]

Today I took S out to walk grandma's dogs - and we visited a park. It made me a bit sad to watch him and see a baseball game going on and know that H is missing out on this. Of course, that's his choice.

I don't know if I should even talk to H. He is still angry - every single time we talk, he throws in 'I need you to sign the [serving] papers'. Do I just not talk?

His LL is words of affirmation, and touch. I definitely can't do the touch he hates it. The words of affirmation though - do I attempt?

My FIL is telling me to ignore him entirely. Like if I walk in a room to not initiate contact. Do I try?
