Doing 180, but Husband still researched D

[Phenix70]

Hopefully someone can give me some helpful advice & how to deal with H & his icy disdain towards me.
When I speak to him, often he gives me as minimal of an answer as he can, sometimes he actually will talk to me.
The one common feeling I get from these interchanges is his total disregard for me, as if I'm bothering him by talking to him.
BUT, when I ignore him & give him the cold shoulder right back, he gets even colder towards me, I feel "damned if I do, damned if I don't."
Anyone able to offer any insight or advice?
Right now I'm going with continuing to speak to him, nothing about us, R or D of course.
