Over a month ago, me (28F) and my boyfriend (28M) of over a year had a fight over the phone (we hadn’t met in 12 days before that so i’m thinking object constancy also contributed to it).

We had a fight upon which i got really angry and i said mean things to him and broke up with him and blocked him for an hour. After i had calmed down and called him back to apologise, he was a changed person. He told me he could never get past the things i said and did and he cannot be with me anymore. I begged, pleaded, apologised, cried several weeks after that but none of it changed his mind. He told me he had a nervous breakdown and went to see a therapist for the first time after the breakup. Now he has finally agreed to meet me but says i shouldn’t have hope of getting back together. 

He was a loving person and i want to be with and care for him. Is there anything i can say to make him want me back again?
