I have no one in RL to talk to about this.
My DH has always struggled with low mood. We've been together 10 years and married last year. Things have been up and down but mostly good. He won't ever see a dr about his mood so he doesn't really have a diagnosis. This is because he is a doctor as well and doesn't think that the GP can offer anything.
Recently he has been referring to his low mood more and more. He has a new group of friends who are lovely. They tend to go out a lot and basically stay out the whole weekend. I like a party but I've never really been into this. They always include me though and I tend to head home earlier than them and DH.
DH has grown close to one of the women in the group, let's call her Lucy. Her boyfriend works away. They often go for lunch together or for drinks. She has always been kind to me and even organised me a birthday party.
However I have grown more and more sure that DH has developed feelings for her. I called him out on it a few weeks ago and he basically made me feel jealous and stupid.
At the same time he is saying that his depression means that he can't promise that he wants to buy a house with me and have children with me. And also that I and everyone around us pushed him into marriage 
He has agreed to go to private therapy to try and help with the low mood.
He was acting quite odd yesterday and this morning I looked at his WhatsApp on my computer.....I am not proud of this.
Messages to some friends saying that I am "not the best at dealing with his depression!"
Messages to this woman Lucy, loads and loads every day about how low they are feeling, how no one understands them. Yesterday he was trying to meet up with her but she wasn't keen and he was asking if he had upset her?? Which explains why he was so odd yesterday with me.
I basically called him out in it. He says that it's "complicated" but didn't deny he has feelings for Lucy. He said we need to "sort this out either way" and also that I shouldn't have bothered him at work.
I feel he should be begging me to stay but the fact he isn't maybe means he does want out?
I am devastated. I'm 30 and I desperately want children. I don't want to split up but how can I stay when he doesn't really seem to care either way?
I don't want him to stop seeing his friends and I feel terrible for Lucy as I don't think she's done anything wrong. But how can he carry on seeing her now??
Please someone come along with some advice!
