Disappointed and frustrated

Hi guys, sorry to bother everyone. So a few months ago I wrote about my depressed boyfriend and asked for advice.

So I tried being supportive as I know what suffering from depression feels like, I didn't want to save him as I can't and I just wanted to show him he is worthy of love.

So when he was having a good day, he would be positive about our future and tell me how happy we will be together etc. During his dark moments, it's the opposite and him feeling as though I deserve better.

He just recently told me that he still has feelings for me and can't have me out of his life, however he won't work on us because it will stop me from finding someone else 😒.

Has anyone else been through this? What did you do?
