<human>: Give me the gist of the text in a nutshell

My boyfriend (23M) and I (22F) have been dating for about 5.5 years. About 2 years ago he started slipping into a depression. I have depression in my family, and also study mental health, so I recognized it right away. I never stopped showing him love and support but he became an absolutely miserable person. He refused to go to a doctor or counsellor and try to help himself, and denied there was something wrong. After a long while, I left and we broke up for 6 months.

During that six months, he smartened up. He went to a counsellor and got help, and things were looking great. He begged me to take him back, he loved me, regretted hurting me, yadda yadda. We did end up getting back together and at the beginning of that, things were absolutely fantastic.

Until -- you guessed it -- he stopped going to counselling, and things have slipped right back to where they were before, and then some. It has been about a year since we got back together. He has completely checked out emotionally. I love him with all my heart and it is so incredibly painful to see him like this, but I can't make him get help, he needs to do it himself.

I can't shake the feeling that I am being so selfish in thinking about "me" in this situation. I couldn't tell you the last time he gave me a compliment, or actually shared feelings with me. I try to talk to him and tell him how I feel but all he can manage is an "ok" or "sorry". When he is happy, he is the the perfect partner and I've never been happier. I want that person back, but I don't know how to help, and can't continue to be the loving, supportive girlfriend who is getting absolutely nothing in return. I don't know what to do.

Yes -- I have checked out /r/depression, but it doesn't really seem like a place that would help me with a relationship issue?
