<human>: My boyfriend and I have been together almost 2 years, seeing each other for almost 3. Rocky start to the relationship with ex girlfriends/boyfriends not quite out of pictures and causing trouble, but when it was finally just us it was bliss. Had a year where it was practically perfect relationship.
He was diagnosed with anxiety/depression about 2 years ago. Stopped taking medications after 3 months saying he was fine.
We've been living together now for 9 months in a shared house (I'm a student, he's an apprentice) and he's recently told me that for the last 6 months he's been feeling alone and depressed and can't see happiness in anything. I tried to get him to seek doctors help but he is refusing. 
He says that due to the depression it's the reason that he hasn't been very friendly to me for the last 6 months. He hasn't been like he used to at all- no showing me that he loves me at all. I'm constantly trying really hard to make him happy, but he doesn't reciprocate at all, blaming it on the depression.
I understand how he's feeling and don't blame him for it, but I don't know how to help if he won't see a doctor. It's becoming really stressful and lonely for me and I'm finding it hard to cope. When I tell him this he just says "stop making this about you" but I'm really not meaning to and just trying to explain how I'm feeling :(

Can you condense the text into three sentences or less?
<bot>: used to have perfect relationship, bf now tells me he has depression but won't seek help and it's becoming very hard for me to deal with.
