Quiet husband causing anxiety..

Mommy
My husband went to go get us a salad, he comes back with a salad for me, and cheap crap to make himself a sandwich. I asked him why he did that... I'd gladly eat a cheap sandwich with him instead of that stupid $7 salad!! He kept saying "don't worry about it". Then he stayed pretty much quiet and mopey until finally going to lay down. He was going to just kiss my cheek, but I turned my head for an actual kiss. He said he seems to get in this mood when he goes somewhere alone at night. It gives me bad anxiety, he did this shit to me after our son was born too and that plus some of our talks caused me to not trust to leave our kid with him. I still can't... I think he has depression, I know I do. He just doesn't talk about it, or about anything for that matter. Just keeps to himself and it pisses me off sometimes. I just wanted to say this I guess, not expecting anything. Just wanted to say something...
