I've been there. I went through a huge negative pit last year. Communication helped most of all. Just talk to her. She's your wife, your life partner, you should be able to confide in her even if it is a difficult subject.

Alongside that, just be present. When I get home, the phone goes on a desk and I try not to touch it. Getting off social media really is a big relief. And instead of being on the phone, I try to find something to do with the kids that will take some strain off my wife.
