He is forgiving, but reached his limitations with my behavior

Been a stressful last month for me and I used him as my sounding board and was too much for him basically because he is my safe place, and thought he could handle things with me, I took him for granted. I feel looking on it now very selfish. I told him sorry, in person, on the phone and in emails. No, he had a ideal childhood compared to me, and never had any exes verbally abuse him.
I offered to take medications again, he never asked, that would be in his opinion my decision not his. He did love me, now I don't know. I feel I pushed him too far and he doesn't want the random burst of drama from me, he said one day all is happy, next an attack for no real reason.
I told him all that and much more, a long phone chat, long in person talk until he walked off, and many long mails. He doesn't want to hear it he wants limited contact now, it's apparent.
Thank you.
