Depression and spouse?

Talking to my husband today and he tells me that he thinks he’s depressed. I myself have anxiety and sometimes get into depressing moods too. But idk how to help him. I kinda force myself out of it until i feel better. I don’t let myself sink too deep. I also smoke (of the cannabis variety...no judgement I’m in a legal state AND my dr said it was ok for me to do since it helped better than pharmaceuticals with no side effects) he’s military. So he can’t smoke. I’ve asked him if there’s anything he’s always wanted to do that he hasn’t done yet. He’s not even been playing his video games very much. And he LOVES them. Usually plays them alll damned day. Now it’s like he doesn’t have the energy anymore.

How can i help him? He doesn’t want to go to a dr. I asked. It’s the first he’s said but when i asked how long he said awhile. He said he just doesn’t seem to feel any excitement or enjoyment out of stuff anymore, not like he expects to.

I wanna help him feel better. I know it won’t go away. But, any pick me up ideas? Something? He’s been great for me since i explained how my anxiety makes me feel overwhelmed. What would be the best thing for him? Space? No space? Activity? I don’t feel like letting him wallow would be a good idea. I think it might make it worse. And i want him to be happy again.
