OK so my husband has seemed really down lately, he has lost all motivation to do anything, he is snappy, tired all the time and basically a shell of his usual self. I'm worried that he is depressed but he won't go to the doctor about low mood as he says he's fine. He clearly isn't. We haven't had sex in 4 months and it's like he doesn't even want to try to make an effort to be around me. He is on his phone every chance whoever he isn't at work and I feel like our marriage is slowly breaking. I don't know what to do as he won't talk to me about what's wrong.
