Boyfriend of 2 years doesn't love me anymore.

So there's this guy. We met at a mental health partial program when I was 17, and we connected almost instantly.He was the first person to ever make me feel like I was worth something. He helped me feel smarter, he helped me feel beautiful. My parents fought me daily and things got really bad. I ran away and signed myself into a group home. I haven't talked to then since.So 2 years go by and me and him are still together. He helps me go through everything. I become really close with his family and his mom is almost like my new mother. Every hardship I went through he was there for me. He helped me stop self harm. Things were great to an extent. He got really angry occasionally. He never hit me or was never abusive, he just shut himself away from me. He suffers bipolar disorder, and recently had a mental break. He was signed into a hospital where he stayed for 9 days until they felt he was safe to come home. When he got out i told him the concerns I had in our relationship and he listened. He changed for the better. He started talking to me about everything and we were getting along great. Literally 3 days ago we were laughing, and cuddling, hugging, and I was the love of his life. Then I had an anxiety attack. And we got into a fight. He told me he didn't know how to help me anymore. That he tries and I shut him down. He said he doesn't think he loves me anymore. And idk what to do because i literally gave up everything for him.
